Google Wave Creator Quits, Joins Facebook
srimadman found an interview with Wave creator Lars Rasmussen where he talks about his recent decision to join Facebook, leaving Google behind. Apparently getting personally pitched by Zuckerberg helped. He says, "I've got a job description of 'come hang out with us for a while and we'll see what happens,' which is a pretty exciting thing." The article talks about Big vs Small companies, and notes that about 20% of Facebook's staff are former Googlers.
His brother (the other guy who made google maps) will stay with google. So it seems that relations between the two internet companies, at least at the top, are not as hostile as they often are portrayed.
