UPDATE: I know a lot of folks are coming here from DIGG and other memetrackers. The $72M someone told me at BarCampLA and I have no idea if that is true or not. If you reblog this (or report it) please make sure you make that clear.
The best piece of information I got out of BarCampLA was that Firefox, which is produced by the for-profit Mozilla Corporation, made $72M last year and is on target to have 120 employees this year. I have no idea if this is true (anyone?), but it makes sense. I mean, there have to be 72M people using Firefox out there, and making $1 a year seems low to me!
