Is bitcoinmonitor.net reliable?

Is bitcoinmonitor.net reliable when it comes to notifications?
(does it crash often/miss some transactions/etc)

Is it advisable to use this service in a real-world e-commerce site? If not what other robust transaction notification APIs (apart from bitcoind) are out there?

It does not seem to be reliable based on the thread mentioned above? What are some alternatives that don't require me to run my own client?

blockchain.info watch-only wallet with notifications enabled

I need to enable my users to send and withdraw bitcoins (more info:  https://bitcointalk.org/index.php?topic=457629.msg5047724#msg5047724)

I looked around blockchain.info (https://blockchain.info/wallet/wallet-faq) to see how it can be a solution.  I do not see how my web app can get a new address from Blockchain's My Wallet, such as an API, in order to show the new address to my user.  It does not seem that Blockchain can notify my web app via a callback URL (https://blockchain.info/wallet/payment-notifications)

When my user wants to withdraw, he will give my his address to my web app.  How do I insert this address into my blockchain wallet?

Am I missing this information somewhere from Blockchain's website?
