That's more or less how I felt about the situation. To my fairly n00b self, blockchain.info has always seemed legit, and seems to be an integral part of the BTC community. Plus it is a one-stop shop for me where I can check blocks for transactions, see charts, etc.
Mtgox was once and Integral part of the BTC community. Think about that and be afraid.
Major scam after major scam has come from Integral parts of the BTC community.
