To be honest - I don't know that steemconnect provides the best way to use the Steem blockchain to power websites. You're relying on a 3rd party service at that point for your authorization and are completely out of luck when it's down. You are also authorizing someone else to actually use your account... which some may not like either.

It's always something that can be added at a later date - but right now not depending on it is a plus in my book.
