Google Gmail has tacked on a 1-line RSS feed reader at the top of the inbox called Web Clips. Most important fact: you can turn it off in Settings. I found it very annoying because, unlike the contextual ads, the content is not relevant to any of your mail.
Anyone else get the sense that Google wants to "do something" with RSS? I hope they do something interesting and relevant, rather than just slap a Yahoo-like RSS reader on top of Gmail.
