Will it ever come back to real-time
this actually brought me an idea for another revenue stream for MtGox, have the site split up into two areas, one public slow lagging stats like they appear now and another paid subscriber membership with ultra-fast reporting, charge something like 0.5-1 BTC per month, offer API for even greater price.
of course Mt is huge and we expect them have this working real-time for free =)
I wonder that is the cause of lagging besides large number of connected users.
