Well, right now, the team is not really trying to market it, since it is super early / bleeding edge.

The design is also in its early stages, and changes quite often.

Ill see if we can get some current screenshots up, or even some of the design docs for what the team is aiming for. (there are also some posted below).

Update :

The team just added a page with some screenshots: https://github.com/adobe/brackets/wiki/Brackets-Screenshots

(full disclosure : i work for adobe)
