@samsmith: You can see this typical SO-family NIMBY argument: "better suited to U&L or (I think) SU or even SO". So move it to U&L and they chase you to SU, move it there and they chase you further. The problem is that this splitting is useful 50% of times and otherwise a crap. You seem to be hitting the latter a lot.

Many thanks to Mark Henderson. @Zoredache: But the niches/purposes are greatly overlapping, the distinction unclear, and the sheer amount of closed/moved question proves it. Yahoo Answers? Are you kidding? Their problem is not having everything in one place, their problems are countless, especially having no tags and no voting. A sort of super-tag could IMHO do here all the needed separation much better than using different URL and different look-and-feel, but this is another discussion.

+1 Nice answer... so the guys derived from the player being intended for non-commercial use that I am a home-user and that's the reason for closing. But wait... what if I was a support professional helping some home user? What if I haven't mentioned "player" in my question? What if I had such a written agreement? No matter what, this is the most ridiculous criterion I've ever heard of. I understand that the problems of professionals and home users differ, but IMHO the distinction is too blurred and makes searching for relevant information harder rather than easier.
