I've been a big fan of Instapaper for ages, and so it's pretty exciting to hear that its creator Marco Arment has transferred ownership to Betaworks (home of Digg, Bitly, and interesting new music collaboration network Blend.io). I honestly don't know what I'd do without Instapaper (it's one of the services I choose to pay for rather than use the free option), so I'm glad to know it's got a great team (with Marco still advising) to develop and direct it.
