My take is that people in the market for a development board don't want a slide show of hero images and don't care about animated images. They care about the numbers: capability, price, and lead time. All of those moving pictures are noise, not signal.

You're competing with the information density of this: http://www.mouser.com/ProductDetail/Texas-Instruments/MSP-EX... and probably not winning with your approach. Because people buying prototype boards are looking to buy from a source that understands their business.

Good luck.
