This Wired article discusses yesterday's Apple Worldwide Developers Conference and mentions that the new OSX update, code-named Tiger, will include a new Safari Web browser with integrated RSS Newsreader:
Jobs demonstrated a new version of Apple's Safari browser with a built-in RSS newsreader. As well as detecting website news feeds, it features a "personal clipping service," which saves RSS keyword searches as bookmarks -- allowing frequent updates of news on topics like "Apple" or "iPod." Jobs demonstrated a search of articles on Vice President Dick Cheney's f-word outburst.
Big stuff for Bloggers! Wonder where Microsoft is on an integrated RSS reader of their own...
