If the data Rich Skrenta is collecting is accurate, RSS is catching fire with Yahoo users. Yahoo recently made it easy for MyYahoo users to subscribe to RSS feeds, allowing them to easily pull content from blogs and other sources into their MyYahoo pages. Skrenta runs the search engine Topix.net and offers news feeds via RSS. Skrenta says they’re seeing about 2,000 new MyYahoo users per day subscribe to Topix feeds. Nearly 26,000 of Topix feed subscriptions are from MyYahoo users.
