I think the threads are already there on the FAQ, but I see plenty of questions that still fall into off topic areas like this, and this question points out some specific flaws.
I'm not sure where to put it, but two litmus tests that I use when voting to close include:
Are we down to a specific set of choices? Quite frequently this is in the new-job choice area. When the asker feels a need to boil it down to two or more very particular, non-translatable options,I generally vote to close figuring that there isn't enough reuse to the answers to make it a viable long term question. My thought for helping it along would be - if you can make it about stereotypical tradeoffs that many people might encounter, this isn't a good forum - we can't be career counselors.
Please validate my choice - Perhaps I'm being too persnickety, but I see a fair amount of "this is what I want to do, is it OK?" Sometimes we can resurrect it into "what's a best approach to this difficulty?" but I see plenty of editing to get it from point A to point B.
In both cases, I can see that we may still be able to help the question asker, but not in the format that it's presented, and I wonder if people are unclear in what they can expect. Not sure, though, that the FAQ can actually fix the problem - people have to read the FAQ for it to be useful. :)
