Looking for the RSS of me

I had an idea today for creating a new website for me. I'm sure this isn't a new idea, but I just don't know how or where I'm going to set this up yet. I have a handful of websites that will creat RSS feeds with my activity. These websites are spread all over the place, I'm going to see if I can create or find a website that pulls all my RSS content from other sites into one common place for others to view.

Anybody know of anything like this that already exists?
