Agreed. I'm not 100% keen on TP, for critique for example, but other than that I haven't seen much problem. Not saying it's bad, but if you post a picture it's somewhat like FlickR ('nice shot', 'cool' etc) rather than a decent enough response. Even the obvious trolls/stupid posts on there don't really get deleted.
Yeah, unfortunately recently there has been a massive influx of this, apparently due to loads of new membersmoaning when people critique their photos. I started a thread and discussion on the very subject a few months ago which indireclty helped the new "critique" tags. Still not as good as it should be and I've given up a little in posting in the Critique sections. TBH I think it's got too big and popular as such, too many beginners asking the same questions (not that beginner questions are bad, just the number of them).
