A new RSS feed reader was launched a few weeks ago that is designed to integrate itself with Google Reader.
WebReader is an Adobe AIR base app, which means it can run on almost any platform. It works seamlessly with Google Reader, and you can use it to maintain a copy of the feeds you’re reading while offline. You don’t even have to tell it what RSS feeds you want to follow; it will get all that information from Google Reader.
It works okay, but I have to wonder if it’s worth the bother of installing. I have to be online if I want to download RSS feeds, so I might as well use Google reader.
