That was fast, I'm glad the update (appears to have) went smoothly. Thanks for keeping things running for us.
Edit: Damn, those usage statistics look way different when tracked in the reddit fashion. I guess that stands to reason, 90% lurkers (other than up/downvoting) is pretty standard.
It still doesn't catch everything since there's users that don't vote comment or post
Adding in users who don't do any action would double it again (although not public info which people are visiting communities hence why its not part of it)
