Just a quick note of the very nice mention of BlogBridge by almost-famous Dowbrigade blog by the incredibly prolific Michael Feldman.
(Emphasis mine, throughout)
Blog Bridge is the amazing new RSS reader and aggregator from Pito Salas. Sure, it makes it easy to subscribe, arrange, view and blog from anything with an RSS feed.
But what really sets it apart is that it is written completely in Java, which means that it is platform-independent, works on any computer connected to the interenet, and it remembers not only what you are subscribed to, but which articles you have already read, or saved, or filed to read later. From anywhere, on any machine.
Being used to the much simpler aggregator built into Manila, it took us a while to discover the utility of moving feeds into channels and groups, but now it seems second nature.
There are suggested sample groupings to get beginners started, pre-packaged packets of feeds, which you can easily modify by adding and dropping feeds. (from Dowbrigade)
Wow, thanks Michael!
