The God Mother of all small bloggers, Blue Gal, has the details. Go there, read up, and participate. It’s important.
Oh, and small in this instance refers to the number of links a blog gets, not pettiness.
UPDATE: to find out how “big” a blogger you are, you can go to Technorati.com and in the searchbar at the top, enter the URL that you are interested in. For instance, here is Mock, Paper, Scissors. The number listed next to authority is the relative size.
