The aggregator service that i use is called ino reader. I was first introduced to it by someone whom i initially met on twitter, and would considerd to be a friend and some one that i learned a lot from. What i like about it is you can get started pretty easy. You could have up on your browser, you know the little buttons that are up on top, those are called extensions. It's really kind of, your imagination is the limit with all the things that you could do with it.
