I was curious what the kudos were, so I hovered over the icon. It told me not to move and started filling up, so I waited curiously. Finally, it counted that as a kudo from me to you!
That said, you have a good point. They really have taken a different road recently with their crackdown on the API. They've got every right do do so, and they're making money doing it (always important for a company), but it would've been really interesting to see the equivalent of an API-based SMS-style nearly-ubiquitous service.
