Rather entertaining contrast in the article:

"we need to chase after ambiguous and unsolved problems; not the problems of today, but the problems of tomorrow. we need to chase after our perception of “the future”."

compared with

"over the next year, i want to focus on consumer web: local buy-sell, event planning, recipe sharing, and reliving shared memories."

Yes, because these are truly futuristic and untapped problem areas. C'mon, dude, try something else.

I take it that the "golden handcuffs" were longer than the 4 months he stayed. Cheers on following his vision.
