These kinds of questions are fundamentally problematic. The best of the lot are those who cop to their complete newness and are just looking for clue. They sound a lot like this:
I'm the developer for this company. The last guy set up the server, but he left a year ago, which means I'm all they have. I am not a system-administrator, but I get to be one now. Right now our application isn't working. It looks like Tomcat is completely locked up somehow, and a reboot isn't fixing it. That's about as far as I can get. Help?
This is a question being asked in good faith, and in distress.
They're also the kind of question where the sheer weight of the troubleshooting contingency tree threatens to topple over and crush my answer under a whacking big pile of words.
These are the questions that benefit most from the Q/A/Q/A/Q/A/Q/A/Q/A style encouraged by forums. Since we're Q/AAAA, it's a poor fit for their needs. Some data can be teased out through long comment threads, but the bigger they grow and the more edits the original question earns, the uglier the entire thing gets (Qcccccccccccc/AcccccccAccAccccccc), and it gets even less useful for posterity.
As a user I only touch these questions if they're close enough to my deep competencies that I can handle the training and troubleshooting required, and the time.
Being a moderator changes the dynamic. If the question has survived long enough to be seen by some of our $Technology experts (it helps to know the active users!) and hasn't been flagged, it's time to give the questioner at least some engagement. Ignored questions are bad overall. Then post a comment asking for more information. If I don't get one, then it's a drive-by and I have no problems closing the question.
If I get a response I'll have a better gauge for their skill levels. Are they a Pee-Wee? Do they have some grind? If the question still hasn't gotten attention from an area expert, it's clear that it isn't likely to get any. At that point, urging them to find paid help becomes more urgent because we can't help them. It's always hard to tell someone, "I'm sorry, I'm afraid I can't help you," but as a Mod it becomes my job to do that out loud.
