Dave Winer has always been the model of class and never the center of controversy. Just because he sends out speaking invitaions to Blogger Con, that are actually sale pitches to get people to buy $500 tickets, does not mean he is sneaky. So he didn't inform his users that he was shutting down the service after he already did so. It's the thought that counts. Let's not forget Winer's public tirade at political candidates not giving money to Winer... er, I mean the internet. Winer is just looking at for the little guy (who happens to look a lot like Dave Winer).
