As ChrisF mentioned, questions need to invite some unique insight from programmers beyond just a simple "I'm asking programmers" clause. In terms of possible scope, we want to hit the blue area of this diagram:

![Programmers.SE scope](https://i.sstatic.net/ociNc.png)

Additionally, real questions invite *answers*, not *ideas*, *opinions*, or *lists*. From [our FAQ](http://programmers.stackexchange.com/faq#dontask):

> You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.

> If your motivation for asking the question is “I would like to participate in a discussion about `_____`”, then you should not be asking here. (You are more than welcome to have such discussions in our [real time web chat](http://chat.stackexchange.com/).) However, if your motivation is “I would like others to explain `______` to me”, then you are probably OK.

> To prevent your question from being flagged [and possibly removed](http://programmers.stackexchange.com/faq#deletion), **avoid** asking subjective questions where …

> * every answer is equally valid: “What’s your favorite `______`?”

I closed it as off-topic per these guidelines: Stack Exchange is not well suited for generating lists of recommendations. 

However, after looking around, I found we had an earlier round that I thought might be helpful (even if it happened to have been closed), so I changed the close reason to exact duplicate to provide a link back to the earlier question.

As others have noted, it's probably a better fit for [Productivity.SE](http://productivity.stackexchange.com) or even [Project Management.SE](http://pm.stackexchange.com), but the guidelines about open-ended questions are a network-wide thing, and lists of recommendations are off-topic everywhere, not just on Programmers.SE.
