Now you can have a link to your blog right in my sidebar. Net Crimes is already there and you can be too! Just click on 'Follow'. Signing up takes only a couple seconds. Invite your other blog friends along.
(ed. note) I believe that if you use another site for blogging (such as Wordpress, LiveJournal, etc.) you can still participate in the 'Followers' by clicking on the text 'Follow and connect with your friends'. This opens a window with other options including Open ID.
