One of the few hassles of using a hosted service for this blog is that, especially unless I want to pay for the top-tier of services, most of which I don't need, I'm mostly at the whim of.typepad for styles and overall themes. A couple of years ago I asked about a mobile-friendly theme, and finally, finally today they announced a responsive design theme!
Heck, I still view almost all my blog content via RSS, but on those occasions I click through I sure do appreciate a site that recognizes I'm on a smart phone. And now my site finally does too. Happy reading!
