Can anyone recommend a good RSS program? [View all]

Google Reader has just announced it's going away in July.

I preferred it to the one I was using before (as far as I remember, that was the RSS feature of my email program, which was, at the time, Mozilla Thunderbird I think - but maybe it was far enough back that it was Outlook Express. Anyway, it had a rather low limit for the number of unread articles per feed, so I switched to Google Reader).

I don't need anything fancy; and I want it to be free (it's a pretty basic functionality I'm after). Has anyone any comments?
