A Google Ventures video about coinbase security with Kevin Rose(from old Digg) asking a bunch of questions with Coinbase founder Brian Armstrong.

Sounds very legit to me.... but... you _still_ shouldn't leave huge amounts of bitcoin in any exchange! Make[1] your own btc-address + private key and keep the coins there. And note that bitaddress.org can be git clone'd and ran on a computer without internet access.

Coinbase isn't really an exchange (though it works as such for US dollars). It's mainly a hosted wallet service that provides apps, and merchant and developer tools to make it easier to engage with the bitcoin ecosystem.
