I'm noticing quite a lot of minor "fixup" edits recently, often in questions that are many months old, or more.
My personal feeling about minor syntax/grammar/layout/spelling fix-ups are that they're great in recent questions, say anything up to a week old; past that, because the edit will catapult the question to the top of the main page, I feel that there's an increasingly high bar to clear in terms of how necessary an edit must be in order to justify the catapulting.
Once a question's over, say, a couple of weeks old, I'm not really interested in minor fix-ups; only substantive factual edits can justify the catapult. For the avoidance of doubt, a posting that's actually become wrong (an important link has rotted, or the author has changed their mind, or new research has invalidated the answer, or the question) is always, to my, mind, worthy of change, and I'm grateful to anyone who takes the time to help keep our content relevant; it's just the keeping it pretty that doesn't move me.
But that's just my personal viewpoint, and it may not be shared. Does anyone else have any strong feelings about this, and if so, what? Or are fix-ups an unqualified good? Or is this so unimportant that we don't need to take any kind of a view on it?
