Since you have so many glowing endorsements and merit is being thrown around within your application thread, I would have to assume that there is something else preventing them from accepting you. I remember theymos talking about looking for sources that are active in obscure board, and maybe the boards you are active in already have a disproportionate amount of merit flowing within them.
I've thought about this too. I mainly read boards that are interesting for me, and indeed, they don't seem to have a lack of merit around there.
Then again, without any official word, we can only guess. I know
more people are waiting, and that list was only updated by theymos once, a few days after merit was introduced.
