From my POV facebook is not a app on my devices but access via the web, meaning html, https, a ton of java and whatever adopted php facebook uses today. What i don't get about this project is why it should need it's own browser beside for the user adaptability that you could technically do via a browser plugin, not to reinvent the wheel all together. Coming from the BBS world i like this idea however, but will miss the illustrations (read pictures). Will however give it a go.
