Marc Andreessen started blogging about a week and half ago. I would have expected him to have started ages ago…

Andreessen was co-founder of Netscape. He then founded Opsware. His latest venture is Ning which is a very impressive social network platform. Basically, you can create your own network using pre-built modules, or trick it out by editing your own version of the source(!) Very neat if you haven’t checked it out so far.

In any case, blog.pmarca.com is a pretty good blog so far and you should probably add it to you reader.
