Google Reader is a great way to subscribe to different RSS feeds because it enables certain social networking features on top of them. If you are "Sharing" with other users then you will see what other users in your network liked and their comments. It also makes it very easy to send links to people via email.
I created an ALT.Net Google Reader bundles a while back that I try to keep updated with different ALT.Net blogs that I subscribe to. To subscribe to this bundle click the link below and then click the link "Subscribe".http://www.google.com/reader/bundle/user/03066432769507324653/bundle/Alt.Net
You can expand the feeds to see what you are subscribing to and even remove certain feeds after you add the bundle. If you have an ALT.Net blog and would like your blog added to this bundle just send me a message on Twitter or leave a comment here.
