I'm talking about questions like:
What tool should I use for x
What language should I learn next
What is the future of technology x
What will be the next big thing in technology x
These questions when they pop up often have the same basic format. It seems to me that it would be better if a warning could be posted at the time to discourage the user from submitting such questions. This would reduce the number of duff questions on the site and avoid them having to be immediately closed or put on hold.
Gnat and others do a superb job keeping on top of these but I'm just wondering if the site could be a little smarter about it.
