Interesting but I question the usability. I read over one hundred feeds every day and to be effective I use a high-quality RSS reader (NetNewsWire). I just can’t see this as being a very effective way for any but the most casual RSS reader to view RSS feeds. In any case, great catch Evan (screen capture available, follow the link):

Since I haven’t seen anyone posting about this, I suppose I will. I’m guessing not many people have it yet, but there’s a new feature in Gmail called Web Clips, which displays little headlines above your inbox or message and is fed via, um, feeds.
