The increase in the character limit of comments has led them to become as important as the questions and answers that spawn them. On several occasions (especially on meta) I've found reason to want to link to a comment directly. I'd imagine something as simple as making the date / time stamp an anchored link which mimics the behavior of the question link.

    It's so weird when fanboys or people involved in something (people who make, use or support something) act like any questioning of the system or feature request, etc., is some kind of horrible attack and they knee-jerkingly attack the heretic who proposes it. I asked an accidentally duplicate question (I tried looking for "permalink"ing comments and didn't find it, so I made my own) and had the same kind of responses. But when they decide to go with it? Universal flip-flopping. In general, I don't like meta.stackoverflow because of this tendency to reject everything anybody says ever. Commented Mar 6, 2012 at 17:36

    I am not sure what exactly @vbullinger's comment refers to, but the Wayback machine shows that even in 2014, this question had comments and 1 "answer" which have since been removed, and in 2010, it was edited to add a "status-declined" tag🙄 In any case, all too true observation😔 Thank you very much for reporting this despite that phenomenon. Commented Nov 10 at 16:55
  • Thanks, @PhilippeCloutier. When I first posted this suggestion, they didn't have comment permalinks on Stack Overflow. So I suggested they do it because sometimes the comments have serious information. A developer from Stack Overflow publicly told that was a terrible idea. Mine was deleted as a duplicate of this one. Then a few months later, the same developer said that it was now supported. But he didn't say that here, so I think mine was the suggestion that was taken :) Commented Nov 13 at 1:32
  • Ah, thank you @vbullinger and sorry, I must have read your comment too fast. The good thing is you can now see your deleted questions (and link to them, although only a few would manage to see them). Which by the way is another pretty good example of a request being "declined"… then implemented. Commented Nov 13 at 2:45

This appears to be officially supported now:

permalink to comments

Right clicking on the timestamp gives what looks like a stable URL:

    It comes from the SE modifications user script. Have you installed that? Commented Jan 30, 2012 at 10:56

    @ChrisF - nope, haven't installed that. Not seeing it on main either and chat.meta.stackoverflow.com/transcript/message/849109#849109 seemed to agree. Commented Jan 30, 2012 at 10:58
  • That is new then. Commented Jan 30, 2012 at 10:59
  • I see that only on MSO and not on SO/SU. Is this a meta-only feature? I can imagine it being a little tricky if the comment thread were folded. (edit: ah.. just read the link to chat transcript) Commented Jan 30, 2012 at 16:40

  • @ShawnChin Oh, weird...it's been enabled everywhere for me since last night, I even disabled all of my extensions to be extra sure (Since I had to update SEModifications to remove this feature). Commented Jan 30, 2012 at 17:29
  • Might also be I have a script cached with a long expiry for main Commented Jan 30, 2012 at 17:33
  • Ah well, I'll try again tomorrow. I'm in no hurry to use this feature. Just curious to see how it handles links to comments that have been folded. Commented Jan 30, 2012 at 18:02
  • @ShawnChin It expands them, then brings you to the comment. That part's been in place for some time, if you go to your responses tab and click a link to a (hidden) comment on an answer, you should be able to see it in action. Commented Jan 30, 2012 at 18:18

    "Right clicking on the timestamp"? Left click seems to work well. With FireFox, after a right click, you need to e.g. "Copy Link Location". Commented Jan 3, 2014 at 17:12
  • @jos yes right click - left click causes a whole bunch of network traffic and loses what I've typed into form controls in Firefox. Commented Jan 3, 2014 at 17:56

    Although this works, it's not obvious / user-friendly. A tool-tip on hover (e.g. "Click to share") would be helpful. Commented Oct 17, 2018 at 14:13

FWIW, you can link to comments by combining the URL used behind the scenes to retrieve them with the internal ID for the specific comment:

https://meta.stackexchange.com/posts/27319/comments#comment-57475

However, this relies on specific aspects of the current implementation, and there's no guarantee they won't change at some point in the future. Don't count on these links being permanent!

Or, even worse, combining the permalink of an answer (to ensure proper pagination) with the id of a comment, which however might not be shown on a page if there's too many comments, or if it's deleted (and hence would result in the page not scrolling at all):

Direct Link to a Comment

Links from the profile page currently use a slightly different format, where the comment ID has the answer ID appended to it (comment-<commentID>_<answerID>): comment-57475_27319 - this triggers a bit of client-side script that'll scroll to the proper answer and expand comments... So it works great, but again: very implementation-specific, so be wary of using this anywhere it has to keep working long-term (at least for now): if the format changes, this won't even be recognized by the browser as a valid ID.

For a userscript that'll make this easier, see the SEModification.user.js available here.

    If you know it's in the top n comments and will therefore be displayed by default on page load, you can use a similar hack: meta.stackexchange.com/questions/5436/direct-link-to-a-comment/… ...But this is even more likely to break, since it's quite possible for a comment to disappear off of the page (too many answers, additional, up-voted comments...) Commented Oct 26, 2009 at 18:30
  • Actually: you currently know it's in "the top n" if it has at least one upvote. Hence, upvoting before linking might currently do the trick, like here... Still then: if the comment is deleted (or if the rendering is changed), the browser won't even scroll to the answer it might have belonged to. So: not really a permalink indeed. Commented Sep 11, 2010 at 11:09
  • Okay, I was wrong in my last comment too. Some posts may have too many upvoted comments, and then even hide upvoted comments... Commented Oct 2, 2010 at 9:57
  • It seems to me that permalinking to comments in the context of an answer would be possible if Auto expand comments of specific answer when browsing directly to that answer were implemented. Still then, deleted comments would not scroll the page at all, but show no error. Also, this might still not work for comments on questions. (And finally: if a comment is close to the bottom of the page, the browser might not scroll all the way down either.) Commented Feb 8, 2011 at 22:10
  • @Arjan: I think it's pretty safe to say that this will never be a well-supported use-case for SO. If you have something important and want to link to it, edit it into an answer (and, optionally, support in-answer anchors) Commented Feb 8, 2011 at 22:51
  • @Shog9 how do I "combine the permalink of an answer (to ensure proper pagination) with the id of a comment" ? I want to link to japanese.stackexchange.com/questions/3223/… (as you can see there's too many comments so it's linking to the wrong place) Commented Sep 25, 2011 at 19:24
  • @Shog9 - Now (2011-09-26) that this is a feature - at least from the profile page - can we assume that comment links are permanent? Commented Sep 27, 2011 at 15:01

    True, but for this you need to get the comment ID first. Commented Feb 7, 2017 at 7:12

    This is sometimes useful when you need to link to a comment but you have to keep in mind also character limit. (For example, when writing comments.) And also in some other situations - for example, in connection with the problem I described here: Links to comments when the title has been edited. Commented Jan 10, 2022 at 5:40
  • This is also useful when using API to link to comments Commented Jun 27, 2024 at 20:20

This would actually be really helpful for people who flag comments - being able to move directly to the item flagged.

I just can't see any legitimate need to deep link (permalink) to a comment.

Conceptually, they are too ephemeral compared to answers and questions. And on top of that, whether a comment is visible or not is completely dependent on how many other comments there are and how highly they are voted, among other variables...

Linking to the question or answer should be sufficient, I think.

edit: we do have a way to deep link to comments now, I believe -- I'll check and provide details.

    You can’t see a reason to permalink to a comment Jeff? It sounds like you’re still thinking of comments as short, not-very-helpful, me-too/thanks type things. Perhaps you should take a look at some of the posts on Meta about comment-answers. Then maybe you’ll see a need for being able to link directly to comments. Commented Feb 3, 2011 at 13:46

    "I just can't see" Says the blind man.... Sometimes I get a response that appears useless except when in context of the comment thread. It's sad that I have to use the browsers search function once expanding comments to actually find the comment buried in what would appear to be a wall of text otherwise. Commented Jun 23, 2011 at 15:02
  • @xaade we explicitly suppress comments and discussion; it's hard for a reason, like driving your car on the sidewalk is supposed to be hard. Commented Jun 23, 2011 at 22:57

    @JeffAtwood: If comments were ephemeral (lasting a short time, is that really what you meant?) then why was the size of comments bumped up to 600 characters? If they are not supposed to be of any importance then why do something that gives them more importance? Commented Nov 16, 2011 at 17:40
  • No, Jeff was right. Comments were intended to be "ephermeral" (short-lived), are easily deleted, and can be removed by someone else by a simple flag. Commented Jan 30, 2012 at 17:11
