Seriously though, I think the amount of merit sources or people actually giving merit is actually an issue right now. I don't really care that much about receiving merit personally because it's useless for me as Legendary now (unless additional ranks or badges are awarded for high merited users), though it is nice to know people have read and appreciated your posts, but there's a lot of quality posts I see that just don't get merited at all. I think even decent/great posters will struggle to rank up to levels of Hero and Legendary if this doesn't change, especially those users just signing up. Hopefully theymos will add users more frequently but this is one more issue that will likely be put on the backburner of things to do but never get done.
Yeah, I've noticed some very good quality posts never receive any merit whatsoever. Its not like they aren't being seen either. There's a few posts in the serious discussion section which I think deserve a few merit. The recent discussion on the tax debate has some interesting replies.
Probably a bad example because they have received quite a bit of merit since I last checked, but there's a few other topics, and replies in that section which seem to just be glanced over.
