Didn't realize we crossed 2000 registered users on our image based medical reference site @ grepmed.com
I still remember how excited we were when we hit 100 users, it was a momentous occasion. I used to check our database daily so didn't realize this milestone had passed us by.
Still have to figure out what to do with all of these emails. Haven't had the bandwidth to email our users but also still wary of spamming busy physicians- a fear I need to get over.
Users are increasing linearly with our traffic (thanks google) so still haven't quite reached a positive viral coefficient, or how to convert more of our users to contributors to the platform, but we'll take this as a win.
