Love it or hate it, Sense is growing up. BlinkFeed, the beating tiled heart of the HTC experience is now being opened up to developers through an SDK. That means that third parties will be able to push information to the stream of data that makes up your feed. For example, Fitbit will be able to keep you abreast of how many steps you've taken without you having to go into the app. Oh, and the Fitbit app does harvest movement data from the phone's internal sensors, just like it does on the iPhone 5S, so you don't really need that separate band. HTC announced one other launch partner for the BlinkFeed SDK -- Foursquare. The location-based social network will pop up suggestions for lunch spots while you're out and about. Of course, the company will have to convince other big names to hop on the bandwagon if BlinkFeed is going to really take off.
