I just watched a very interesting interview of Marc Andreessen on Charlie Rose. Marc Andreeson is one of my favorite technology people. I was lucky to meet him and have a short conversation with him at Startup School last year.
A couple things I didn't know:
The Mosaic web browser was developed at University of Illinois by Marc Andreessen and Eric Bina in 1993. Marc left the University and went on to create Netscape Navigator (which eventually became Firefox). What I didn't know is that Microsoft ended up buying the Mosaic code for $2 million and renaming it Internet Explorer. So Marc actually originally wrote both browsers.
Evan Williams is the guy who started blogger.com, but did you know he also started twitter.com?
