My next RSS Client

Yes, I have RSS on the brain. But as I think of the ways I would like to use RSS, I keep coming back to the same place. I need RSS and email integrated into my Personal Information Manager.

Because I’d like to tuck individual items away for future reference and execute a combined search over my RSS items and email. And I’d like to get a meeting announcement via a RSS feed and easily add it to my calendar. And have modifications in the meeting time and place propagate to my calendar.

I wonder who is going to step up to the plate on the Mac?
