I wonder how those stats compare to Reddit now, or how they compare to digg and Reddit when the initial transition was happening

first I wrote

Is there a good way to scale the X axis? 7 days is meaningful but I'd *at least* like to see 1M and 6M.

I clicked Home which helps, but view options would be nice.

I read at some point the definition of active users here required posting, while reddit cites users as unique visitors. Anybody have insight on this?
