For the past few months I have been waiting on bloo too to be released because the official fb app is terrible. Recently, dimitris, the dev of bloo, said that he might have to call the app dead. He also hinted on his website that he would like to see some devs pick the app up and finish it up, polish it off, etc.
This is a great app and I think the open source android community could create the best fb app out there!!
Sadly I don't have any skills in dev, but I wouldn't mind helping with testing... haha
