I got tired of those advertisements in the right bar, because they didn't pay off at all. At least with the service I was using. And as I don't really like advertisements anyway, I don't like to search for another provider. Anyway, I thought it might be much better to integrate the flattr and donation-buttons there, as well as a Twitterwall, to connect the community (Use the hast-tag #osb_cc for twittering). What do you think of that?
