Agreed. In the word of "the dude" - "You're not wrong, Walter, you're just an asshole".

Asshole is probably too harsh a word, but considering that "futurestack" was already taken as a domain and as a twitter account and both were in active use and related to technology, naming your conference "futurestack" seems a bit lame. Perhaps they could have done more to communicate what the official domain / twitter accounts were. (i.e. make them more prominent)
