Follow and No Follow

I am sitting in front of computer...don't know what must I do. Actually I like blogging,but I have no idea want to blog about what.What I do is log in to forum and saw a lot of reaction people about dropping pagerank.

A lot of people talking follow and no follow. Actually I am not so familiar about this one.And following what people said about follow and no follow made me had a headache ha..ha..ha..
