That thread title raised my interest, core. Some time ago I raised a thread on the subject. Undoubtably, wandering from thread titles is ,imo, more prevalent on this site than others I visit.
Off title threads
However, as a result of the feedback, which you can read there, I decided I was in a minority and could lump it or leave. Nothing has changed since then.
Yesterday was a prime example of such, and an (again, imo) extraordinary display of bad manners. A new poster was earnestly requesting some help on a bsod issue. Right in the middle of the help, another member popped up with a totally irrelevant joking remark whiuch was immediately followed up by a similar response. The OP has not, so far, responded, but I can see he is on another site with the same question (I believe it is he), so maybe we will not see him again.
