Is there a place where I can compile all my blogs in just one site?

I have a scattered personality on the internet. I've started and forgotten several blogs in the past and I would like to compile them all in one place. I want to feel less schizophrenic. It's great if it will be a free blog (CHEAPSKATE!) but I'm also OK with paying. As long as I can continue and compile them all seamlessly. Any suggestion will be welcome and appreciated. Thanks in advance!
