That reminds me of Biz and Ev of Twitter talking at Startup School about when they were first playing around with it (I wish I could remember how it was described).  In essence, Biz said that it was neat but not very useful to which Ev replied "neither is iced cream".<p>Just because it's a toy and not a tool doesn't mean it's worthless.<p>Edit: After re-reading your post, I'm not sure that is what you were saying.  Apologies if I misrepresented you.
