Interesting -- I was wondering about that. I suppose it'll probably fluctuate pretty wildly from time to time.
I'm planning to take a peek at the beem library in the next couple of days and see if I can't wrap my head around the account claim process. I keep talking to some co-workers about the dApp I'm working on, and I'm almost ready to start trying to on-board people (people that have previously tried to get through the 7-day wait at the Steemit sign-up process, and have either been forgotten, or forgot about it themselves).
