I've been wondering when one of the well-known RSS/XML engines (Feedster, Technorati, Daypop, Bloglines*) was going to be the first to offer a version of their service for mobile browsers. We now have an answer.
Technorati's mobile home page consists of a search box, a list of the hours top search terms, and links to top stories in three categories. Results pages do not show paid links. Caveat: Although the Technorati search interface and results pages have been optimized for mobile browsers, many of the underlying blogs/news services that Technorati offers links to have not been optimized. This doesn't necessarily mean that you can't view these pages/posts but does mean that the formatting might. I'll be interested to see if Technorati begins converting blog posts (similar to what Google and Yahoo offer) into a mobile friendly format.
