SalesForce on a roll - Heroku, Do.com, and now Desk.com

Salesforce just launched Desk.com, their revamp of Assistly (which they bought).  As a quick recap, Assistly was a cloud-based platform that allowed businesses to do integrated customer support/management across most asynchronous modalities, viz., Twitter, Facebook, Email, Phone, IM, etc.  SalesForce bought the company last year.

They've pretty significantly redone the GUI - making it vastly more mobile-friendly than it used to be (The mobile version is mostly, if not completely HTML5).  From what I understand, they've also retooled the back-end, basing it all on Heroku a-la do.com.
