There were some comments on pricing that I'd like to comment on: As a one man startup that's fully self-funded I deeply appreciate the prices that aren't straight out of Sillicon Valley. I believe in free market and really don't mind companies doing profit first, but those are often services that simply are out of reach for the more budget conscious of us while adopting new technologies.
Let me thus petition for keeping a small enterprise plan in the price range you're now at, maybe limited by nr of employees, company age, and/or even easier, the number of subscription months/years. That'll give us a chance to adopt your service while increasing the value we get from the service.. When the value's there I won't hesitate to pay a higher price for it either.
