<p>I feel like questions along the lines of, "my printer is crashing for no obvious reason, what should I do?" may be too broad and open-ended for this format. It's better handled by a forum where people can have running discussions to rule out a series of tests. What do you guys think?</p>

For common problems that get asked a lot, I wouldn't just close these as
too broad.
A better solution is to create a
canonical post
like this:
How do I troubleshoot when I have no clue where to start?
These attract a
lot
of users.
The goal is to create a step-by-step trouble-shooting guide to explain what lights, nozzles, and sneedles to look when you're kwigger isn't going
zong.
And don't just answer with a hyperlink to some other discussion group somewhere. Do everything you can to really overkill it. Write a detailed, step-by-step, ultra-clear guide, so when zillions of people with this problem go searching, you stand a good chance of the best possible answer on the web.
This is one of those opportunities to attract some great new users who will add value for years to come.
