Blockchain.info has a good amount of security breaches since it started. Most of them are due to the developer's negligence and not ensuring the methods used are foolproof. If a person judges the trust based on the age of the product, it would be totally wrong. Even though it is opensourced, the track record should show their efforts put in to secure the customer's funds.
If they used random.org as a process for generating their RNG, they could ask the site to give them updates on the changes made or at least, monitor and debug their software regularly. [Bug existed for more than 5 months]
I didnt suggest blockchain.info to anyone though that wallet was the wallet that was suggested when someone asked for a online wallet. Its not a wonder when all online wallets left and right got "hacked" and otherwise vanish. I remember things like ultrasecure wallets, best security and all and... hacked. So people tend to suggest blockchain.info because they still were there and they thought they would have fixed problems over time.
I mean lets say you want to bring bitcoins near to someone. You cant make him download something if you arent there, its easier to give him the login to a wallet and thats it. Giving bitcoins to a noob would mean risks anyway. No backup, no antivirus and so on.
Too bad. I didnt know that its SOO bad.
