There's nothing inherently wrong with questions that seek advice and wisdom from those who have more experience than themselves. And there's nothing wrong with sharing that wisdom here, if you can…
…back up your statements with constructive, sound reasoning.
But where these questions go wrong is when they become so generic as to stop soliciting hard-earned wisdom and veer towards simply polling the community.
The blog post Good Subjective, Bad Subjective should be required reading for this community.
The earmarks of bad subjective is when the answers fill with "I did this", "I did that", and "I did blah blah blah" responses. When answers don't even purport to explain why their solution is better than any other, it goes from being Q&A to just a poll of the community. Overly broad questions are just soliciting a collection of random answers. Folks will vote this stuff up, but it's just not good Q&A.
The Trouble with Popularity
It's a tough sell, but if you want this site to survive, you need a place where people are asking very interesting and challenging questions, not the uninspired poll questions that have all been asked 100 times before on every other site on the subject. If this site wants to rehash the same old conversations found in any random message forum, there's really no point in trying something different here.
If we can avoid questions that are simply asking, "Let's hear what everyone has to say about…", we can maintain the ideals of great Q&A in the face of completely subjective topics. This is especially true early in the beta when the site is new. The earliest questions on a site will set the tone and topic of the site for a long time.
