Hey,
I like to skip across Blogit clicking on random blogs to see if I can dig up a buried treasure. Still, I've noticed that however unbiased you are, the blogs that come up are inevitably the most popular. My experience is that popular does not necessarily mean good. The thing that is most important for popularity is the amount of comments that are given out by the said person, and the number of updates, i.e. the amount of time spent on Blogit.
So how about this: A Buried Treasure link, that gives you one completely random blog every time you click on it, up at the top where you can click it every time you want a new blog to look at (without clicking back to the homepage first). It might be a little bit of a step up for those with less time to spend on Blogit at least, as well as being a highly amusing way of getting something new whenever you want it.
