Yep, it's working fine at the moment. You need to create an account at the Feather site. You can connect to any Feather or Earthlink AP and refresh your RSS feeds whether you have an account or not to either service.

The current APs available to me in my area are:
FeatherSecure
earthlinkwifi
FeatherByEarthLink
WirelessPhiladelphia (service provided by Earthlink)

With the exception of FeatherSecure, connecting to an AP and trying to visit a webpage brought me to a Feather site to log in. After logging in I was able to browse from any of the above APs so it appears there isn't any disassociation with the networks here yet. I'm guessing it logs your session and keeps it alive until you're inactive. I believe I read somewhere that it said after five minutes.

Pretty neat to have free wifi for the time being!
