Looks cool. I will try this out later.
FWIW, a few suggested changes to the icons you're using:
1. For the feed, I know you hate it, but consider the "rss" icon. Alternatively, there is another "signal" icon that, while emulating the Mac's WiFi signal icon, is cooler looking (IMO) than the cellphone-inspired "signal2" icon. "wifiAlt" is pretty cool, too.
2. For redirect, instead of using the universal "refresh" icon, consider the "direction" icon or "newWindow" icon.
3. For the howto, instead of using the same icon as a blogpost, consider the "lightbulb" icon.
