That’s right, Thunderbird. The RSS Reading experience is dead simple - you subscribe to a bunch of feeds, and they show up as mail folders. New postings appear as new messages. Couldn’t be easier or simpler.
‘What was wrong with the other readers?’ Nothing significant, just enough for me to want something better - and there isn’t any point in running them down as the issues I had were minor - if you’re looking for an RSS Reader, I’d recommend both, as you’re unlikely to run into the issues I had.
