This coming on the heels of their decision to unlock all of its boot loaders shows that they are at the very least taking notice of the developer community. This will be great if it allows developers to customize the actual inner works of sense.
This is going to be interesting because Sense in general, is HTC's proprietary software. People should not be confused to think that all of Sense is "open". An SDK (Software Development Kit) is a totally different thing. It makes developing for Sense apps if you will (themed for Sense, using Sense features, etc) much easier.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
