I LIKE it!
I know you get a ton of requests for improvements, but tighter integration is high on my list. Most every 3rd party DNN authentication and registration module provider has integrated to twitter and Facebook. I love what you've done with Twitter and hoping FB is right around the corner. FB to AS and AS to FB status updates seem like a must have now, especially with the strong FB API that is available.
There is a work around for those interested. Its kind of kludgy, but works nonetheless. You can now configure your FB account to automatically have your tweets posted to your FB wall.
