Putting aside the chatter about A-listers vs. Z-listers, the challenge of finding interesting blogs has taken a turn with the launch of Blogcode. Based on the "if you like this, you will probably like this" approach, BlogCcode generates a list of recommended blogs. While BlogCode tries to be straightforward, I found the instructions somewhat confusing. I'm not sure, for example, if I need to provide reviews on other blogs that I like or whether I just have to give information for my own blog. Perhaps this will evolve once the beta moves forward. In any event, BlogCode is trying to crack the nut of how to find new and interesting blogs in a different way from Technorati, Blogdigger, IceRocket, et al. Blogcode appears to a combination of traditional blog search and blogrolls. I'll keep an eye on it but it's leaning towards cool but only somewhat interesting status.
Update: Technorati has quietly introduce an "authority" tool, which works by measuring the number of links into a blog post. I found the authority toolbar difficult to manipulate and the results are mixed. This thing should have stayed in alpha or beta for a little while longer.
