The entire world is now a rival to Silicon Valley. No country, state, region, nor city has a lock on innovation in technology anymore.

I also like to use a sensational headline. Many people read blogs in aggregators, which generally show only the headline. So you have to give people a reason to click through. Blogs need to be real and personal. Reading it should be like hanging out with you. I play music for my readers. I show them videos I like. I tell them what I did over the weekend. And I tell them what is happening in the technology, Internet, and VC markets.

My venture investing career has three phases, all roughly 6-8 years long. The first, at Euclid, was software to Internet. The second, at Flatiron, was Internet to bubble. And the third, at USV, has been web 2 to mobile. I have always used a new firm to denote a new investment phase for me. Throw away the old. Start with the new.

Being an entrepreneur is hard. Having supportive and caring investors helps.

Facebook is not an unstoppable juggernaut. There are a lot of other things people can do on the web.

If you have an idea that you can't get out of your head, do a startup. Otherwise join a startup.

Markets come and go. Good business don't.
