Integrated RSS in Yahoo Mail (Beta)

Over at TechCrunch,
"Yahoo gathered a small group of bloggers, press and others at Sauce in San Francisco tonight to announce the launch of two new RSS products. They have integrated an RSS reader directly into Yahoo Mail Beta, and are expanding Alerts to include RSS feeds."

I think that this is a very good move from Yahoo and I am now eagerly waiting for their new platform. I believe that google missed the chance to push their gmail platform. Instead of launching a separate reader, they should have integrate it within Gmail. If people can spend money for getting integrated RSS feeds in their Email client, why would they not use Gmail for that?
