As a technologist at feel at times that web entrepreneurship is all about writing: most entrepreneurs I have met outsource coding to someone else and all they do is write: blog posts, tweets, emails to investors, answering support forum questions...

It's common to hear stories that begin with "Sergey and Larry..." but I doubt those guys spent any time blogging and tweeting about how awesome Google was going to be. Just one more reason to be more like S&G, that's all :)
