Jon is an awesome dude, and a great person to work with. In addition to having the best hair in all of The Mission, he and his team will no doubt go far in the only storefront sector. Can't imagine a cooler founder to work for!
Absolutely agree. Much easier to tweet a page WITHIN Safari rather than copy the URL, move over to a Twitter app, then post it. Great feature, for sure.
DocumentUp is something similar, which pulls the readme and automatically makes a beautiful wiki-type document for any git repo.
