True. I could also walk over to the place and tell them in person (after a flight and a drive etc). My thoughts are that if you are asking people to volunteer to contribute, expecting people to sign up to a third party in order to communicate is not "frictionless". After all, there is thing called email that's been around for a while and is used by, pretty much, everyone. Also post forms. The main reason for using Twitter (my belief) is to get your users to promote you for free.
