Does it seem like every other post here comes from the SF Chronicle? That’s because the Chron offers several RSS feeds of which I am subscribed to seven. I also get feeds from the Mercury News, Ars Technica, The Register, and a number of others. Gone are the days of poking around several news sites every day looking for stories of interest; gone also are daily email newsletters filling up my inbox and confusing my spam filters. The wonderful Opera browser includes an integrated RSS client so everything comes together in a single interface.
