I found some time to sign up for the new service today, and I'm really blown away by it. For a start, it's much quicker than it used to be (not that the speed ever bothered me much), and there are loads of new features like combining feeds, slick templating features, and a host of different output formats.
The free account gives you up to 5 digests from up to 3 sources, so you can try it out and see if you like it. I think you'll be hooked. Apart from anything else, it's worth signing up just to see Peter's wonderful way with Ajax alert boxes. Needless to say, I'm jealous.
