Great Stuff, thanks.
While I personally do not object the publication of names, some may object their name being associated to a specific bitcoin address (which anyhow should supposedely be known for any legit transaction--- Furthermore, people can put whatever name they wish, right?). So bottomline, I tend to think publication of names is okay. Let's hear what the rest thinks.
As soon as updates on the app allow me to do something in facebook (as I mentioned the facebook button just crashes the app in iOS 5.1.1), I'll be happy to comment on that.
