Well, taking out the weather option ... I hardly ever do.
If I'm looking at a specific technical problem, then a scan on a source I'm not allowed to cite here, it seems, or some such may give me a hint as to whether it's going to be any help to me. If it is, i continue. If it's isn't, then i'll go away and decide whether I should pursue the problem or not (ie am I wasting my energy here ?)
I suspect, though, that I'm not representative of users.
