https://blockchain.info is an informational website that displays information from the Bitcoin blockchain, economy and network, such as transaction data, mining statistics, node information.

https://blockchain.info/wallet is a wallet service. It is a browser-based wallet written in Javascript. It is different to some other browser-based wallets such as Coinbase in that you control the private keys to your Bitcoin yourself.

The advantages of this are that blockchain.info is easy to use and requires no setup, and your encrypted wallet is stored on blockchain.info's cloud, so you can access it from any computer and you control your private keys.

The disadvantages to this service is that you are entirely dependant on blockchain.info, if the website is down you will need to install another wallet and import a backup of your blockchain.info wallet in order to spend your BTC, if you did not keep a backup then you would not be able to access your wallet, and blockchain.info is frequently down. Also blockchain.info knows everything about your transactions, while they claim not to store this information, it is still being sent to their servers whenever you use their wallet.

Another disadvantage is while you control your private keys, a change to the code on the blockchain.info website, by malicious staff or by a hacker, could easily steal all your Bitcoins.

Another one is that blockchain.info is written in Javascript, it needs to be in order to work in a browser, and Javascript is not the right tool for cryptography. It is easy for blockchain.info to accidentally introduce a bug that could lead to your private keys being stolen. This happened very recently to blockchain.info and lots of Bitcoin could have been lost, but a good guy managed to use the bug to transfer the BTC out of peoples wallets before a bad guy did and he gave it all back to blockchain.info, preventing the Bitcoins from being stolen.

I had one problem with a blockchain.info wallet, but apparently not the same one as Blazr referred to.  I had a wallet there, but one day I saw that everything had been sent out (this wallet had 2FA "protecting" it).  There was also a "Public Note", instructing me (and many others) to contact blockchain.info.  My wallet and the others who also had BTC sent out all had the same wallet as the receiving (thieving?) wallet.

I did contact them, and after a little back-and-forth (not bad), they told me to open another wallet, with another password and to never use the old one.  I did what they said, and everything then went fine.

*   *   *

I now use blockchain.info wallets only for transactions and mixing (their SharedCoin service).  I also use their "Second Password" feature (look to the "Settings" to find out how to use that).  The second password is used to send money out (or to get another address).  The second password is typed in via a "virtual keyboard" displayed, a little like Trezor's password prompt.  That helps keep the keystroke logging programs at bay.

Blazr knows a lot more than I do.  But, some of blockchain.info's problems do indeed seem to be bugs that they inadvertently introduce when tinkering with their coding.

Still, I have switched over to Ledger and Trezor hardware wallets for larger amounts of BTC I want to keep in cold storage or keep around for larger purchases.  The hardware solutions seem to be much safer.
