BlockChain.info provides two great services. First they offer a block explorer so that you can check the status of sent/received transactions as well as the balance of bitcoin addresses. Just enter any address into the search box at blockchain.info to see how this works.
Secondly they offer a free web based wallet service. I recommend their web wallet as many people use it and transactions between blockchain.info wallets will be instant. They also have an iPhone and Android application to make sending and receiving bitcoins on the go quick and easy. I don’t recommend keeping large amounts of bitcoins in an online wallet, rather just a few for everyday stuff.
