Lift - http://lift.do/ - tagline is "achieve anything" - give us your email. Nothing else.
Branch - http://branch.com/ - was on HN the other day and has a pretty video, but I have no idea what they actually do as a product/service.
Medium - http://medium.com/ - despite the nice blog post, I still have no idea what they do.
Ev & co are undoubtably talented and they're working on what seems to be some cool stuff, but I feel like I've read a bunch of stuff about what they're doing and still have NO IDEA what it is they're doing.
Is this just me?
