If you had a lot of friends who had blogs on different blogging sites (like WordPress, Google Blogger, Moveable Type) you would generally have to go to each blog’s Web site every day to check whether they have posted any new blog entries. That would be a waste of time (especially if your friends didn’t post blog entries very often).

What information technologies could we use to make it easier to keep track of when new blog posts were made and which blog posts we had read and which we haven’t read?
