I don't see much point in the convention, but I didn't see much point in prefixing node titles with ones nickname either, even back when Newest Nodes did not display the name of the posting monk. I think my main point is, that since Anonymous Monk initiates a lot of threads, there won't be much effect of the convention. But then again, I read most of Perlmonks and I'm not necessarily on the hunt for "unsolved problems".
