I have been an advocate of
RSS ever since I discovered it. RSS allows me to keep up with the news on many topics while losing as little productive time as possible browsing many websites.
Having used many RSS feed readers, I have been consistently disappointed by the lack of synchronization support for read articles and tagged items across computers, as I use many different systems throughout the day.
Google Reader has this feature by its nature of being a web application, but oddly for a company specializing in search, it didn't have feed searching, a feature I use constantly. I have switched between
RSSOwl and
Newsfire, liking the rich client features, continuing to be annoyed by the lack of multi-system sync, but not annoyed enough to write an RSSOwl plug in to do it for me (one of those things I would enjoy doing if I get some free time).
Yesterday Google Reader added
feed searching along with other useful improvements and refinements.
