Lessons From Kazaa


Published on

At the end of 2008, I attended an inspiring mini-conference in Palo Alto for CTOs to jam about big ideas. The conference was hosted by MIH/Naspers and over the 3 days we heard inspiring talks from Werner Vogels (Amazon) and Jason Hoffman (Joyent) as well as representatives from QQ (China), GaduGadu (Poland), iBebo (India). I learned a lot and met some great people.

This is my keynote on some lessons I learned at Kazaa. It was great to be amongst a crowd that managed bigger communities than we served at Kazaa and felt incredibly retro to discuss tech that was so 'old'.
