An MSN spokesperson confirmed that the start.com services are similar to the MSN Sandbox site for incubating possible MSN services. "Now that MSN has developed its own search technology, the MSN Search product team is quickly developing new features," the MSN spokesperson said in an e-mail. "And this is just something the team is playing around with."At this point, there is no timeline or plans to formally integrate this feature, as it is still in the development/testing phase."Yahoo was one of the first major online services to embrace RSS, offering aggregation through My Yahoo last year and providing links for RSS feeds within search results. Last week, it took its RSS strategy into the mobile arena. Yahoo added My Yahoo headlines, including those from RSS and Atom feeds, to Yahoos mobile service. "It seemed like a natural progression to take the power of RSS and let users take it with them and extend it beyond the desktop," said Scott Gatz, Yahoos senior director of personalization products. Users with mobile devices supporting a WAP (Wireless Application Protocol) 2.0 or HTML browser can view their news feed subscriptions from My Yahoo. On WAP phones, users can view the first 1,000 characters of a post. On HTML-based mobile browsers, they can also click a link to the Web site or blog, Yahoo announced. As for My Yahoo overall, it now has millions of users accessing news feeds and has increased the number of feeds in its searchable database to about 250,000, Gatz said.
