You can search for high .edu blogs for comments and soak up the link juice It's also a great search engine for general curiosity stuff like green house effect or how stuff works or whats the latest in computer tech without all the commercial hype you get on affiliate .com sites. Their .edu search looks a bit basic but the quality of their index is anything but! I think the yogoe people have collected are good percentage of all .edus out there cause I'm yet to see any dot com's or net's and the such in their index. I found a heap of dot edu comment blogs there and scored some PR 4 and one PR 5 comment link. It's impossible to do on google this because they show .net's, com's, info's, org's etc in the results. Here's their link, Yogoe.com Dot .edu Search Engine help it's as helpful to you as it is to me enjoy!! ROOFIS
