A good idea, and one I had myself recently.

Some suggestions: I know none of us like "the algorithms choosing", but I think we can do better than alphabetical order. Number of clicks you see (popularity), or number of inbound links google tells you about would be good.

I also think you've gone to great effort, but it's still very light in some categories. I hope you keep going - what's your data source? Are you tracking outbound links from the ones you have indexed to find new blogs?
