Ah yes, good points there. Yeah, it really depends on the ratio of newcomers to oldcomers. Oldcomers get annoyed when they have to answer the same questions over and over again. Of course, they could just downvote and move along (in fact, it usually doesn't cost much effort to do that). But for some reason, they get annoyed (it might even be irrational to get annoyed so easily, but lots of people believe that it's hard not to get annoyed - and they often justify their annoyance).
