Try going to the homepage. On the left you will see a bunch of popular tags. Click on one topic that interests you. From the list of posts find one that you really like (go ahead - click a bunch!) then look at the people who have replied to that post. The people who reply to the posts that you like are the people who have similar interests to yours and there is a better chance that you will find content that you like if you follow the commenter home to his blog. Look particularly for commenters who have something interesting to say about the topic of the post. When a commenter knows something about what they are talking about there is an even better chance of finding gold!
