Nudge.
I'm launching a social network with some of the same functionality and
would like the same thing. Users don't want to leave their eave
usernames and passwords in the hands of a third party if they don't
have to. Every time if an app tells me it wants my facebook username
and password, I just close it and never go back.
I'd also like to be able to do shoutouts in a non-hacky way. Right
now it takes jumping some hoops to make it work. It'd be nice if it
were just a simple API call, and better yet if I could add a shoutout
to the Buy method. It's been coming soon for a while now.
