I think the marketing has been lacking a little. Even with the current code Memorycoin is quite original and hasn't been rewarded for it. I think it got lost in that January craze of new coins. As soon as the price picks up and the officer's salary becomes noteworthy i'm sure people will get interested as well.
Hopefully a little bit more activity on bitcointalk forums will bring other smart people on board!
Agreed, more bitcointalk activity is definitely needed.
Or maybe some people are ninja buying

Any way I'm to lazy to parse square forum, so some resume here from time to time would be good.
