What Do You Do?

So...I'm feeling the need to streamline, cut down on things, simplify. I have a website - well, 3 actually (one for me and the two pen names I was considering - just in case I needed them :) ). But I don't do anything with them. Everything is pretty much on my blog anyway and more people come to my blog. Soooo, I'm thinking I might just combine everything over here instead of trying to maintain different sites.

What are your thoughts on this? Do you guys have separate sites or do you just keep everything in one spot?
