I paid for Feedbin for quite a while, but it had too many issues/missing features. I replaced it with nothing, unfortunately.
(I think at the time it was one of those Sod it, I'll write my own moments, and of course never got around to it.)
Admittedly mostly as a result of no longer using it, but currently the only source I read regularly (by email) is Levine's Money Stuff. If I could get his column and some YouTube 'subscriptions' by RSS, I'd be in.
