Apparently it has not eliminated up all instances of junk appraisals, but in my observations the new Q&A requirement has improved overall quality quite a bit. If I come across appraisals like the one wot mentioned and that user's other appraisals are along the same line (short or spamlike w/o explanation) then it only takes me a couple of clicks to unapprove them to earn NP$ for appraisals. I can't be everywhere though, so drop me a name if you see something you would consider appraisal spamming.
I posted a "Newbies Guide to Appraisals" at
http://www.namepros.com/showthread.php?t=82655 that describes some good methods of offering constructive opinions even for those without extensive backgrounds in valuating names. I'm trying to give everyone a shot to earn NP$ for appraisal posts, regardless of experience.
Thanks for the input,
RJ
