Since JotSpot's acquisition by Google at the end of October, their homepage hasn't changed from "We've closed off new account registrations while we focus on migrating to Google's systems." Their blog hasn't been posted to, and the support wiki seems inactive (save for some users who are worried, due to this lack of activity).
Granted, it's only been a couple months, and these sort of transitions take time. But considering what happened to MeasureMap—i.e., dead in the water, a year after acquisition—and the fact that using/developing on JotSpot takes a nontrivial commitment, some communication to users (formerly, paying users) seems appropriate. (Come on guys, they'll let you do an insignificant blog post to show you still work there!)
