Why doesn't anyone know how to ask a question around here?

I'm really more and more interesting in helping out folks through this website. It's great. However, I would like to be able to help more of them, but many make it impossible: They do not provide anything but the most basic information! People with computer problems state the problem, but no info as to their operating system, the name of the device they're having problems with or anything like that. Problem is, I can only state in the answer that they need to provide more info in the future, but no dialog is possible. But I guess that's what forums are for ... still, it'd be nice to be able to do it here.
