Hey me.mark,
Thanks for the great feedback. (And your comment on the other thread made me smile. Much appreciated!

)
Our philosophy with respect to OpenFeint was to keep it as unobtrusive as possible. People who know/use/love OpenFeint will be happy to have the feature and know how to use it, while those who don't care about "social gaming" probably, well... don't care.

But it's true that many people will be curious enough to tap on that icon, and will be wondering what it's all about. Hmmm... I'll think about how we can add a little more info unobtrusively.
Thanks,
Eddy
