I’ve given up Radio Userland’s aggregator. I had to do it cold turkey, but I did it. I tried SharpReader for a week, and while I like some of the features, like 410 GONE support, it’s much faster to read the headlines in a single long scroll than it is to click about. Same thing with Newzcrawler (and the Ouchlook integration issues), NetNewsWire, and FeedDemon. They’re all good for a leisurely read every now and again, but when you’re scanning and deleting lots of lines, they’re just too much work.
On the recommendation of several people, I’m trying Bloglines. It’s nice. It’s fast. And it fails when the network does.
