Jeremy Zawodny points out that My Yahoo! has released to public beta testing the RSS module that slipped out accidently a few days ago and was then quickly hidden again. Now, we can see that it was worth waiting for.
I've updated my own My Yahoo! page to include a few links to custom feeds that I defined using our custom feed generator service and am very pleased with the results. Now, I've got my most interesting subscriptions on the same page with my personal stock market information, news, weather, photos, etc. I've got a single "dashboard" that gives me a quick snapshot of the Internet-available data that is most critical to me at any moment. Cool!
