+1 for Google Reader… I use it to follow about 125 different sites and blogs. Think of it as your own personal newspaper, that updates real time, with only stuff that you like. Plus the interface works decently on my iPhone. Finally, it also helps with sites/blogs that you find interesting but don’t update much. Instead of having to go out there everyday to see if there’s a new post… it just grabs it for you.
Here are some feeds that I follow:
