Steve has a monthly newsletter you can subscribe to, a Twitter feed you can follow, podcasts you can listen to and even a Facebook page you can "like". He offers many great tech tips for beginners and more experienced users too. I also like his "Dotto Demos", short video screencasts that explain a whole range of applications.
