Hi. Long time lurker first time poster here.

I, like many other people use blockchain.info online wallet. So far I've had no problems, all transactions have been fine and it is a very convenient way to keep my BTC.  The reason I decided to use blockchain.info is that I've heard about people getting hacked, losing their computers, forgetting their private key etc. so I thought blockchain.info online wallet would have someone who's full time job it is to ensure the site is secure.

What I want to know is how safe is the online wallet at blockchain.info? I guess there is no legal guarantee that the bitcoins are safe but how trustworthy are the people behind it? What are we getting when we get a online wallet?
