We’ve introduced an updated version. New features include 31 extra feeds (all of the mathematics feeds at www.arxiv.org), the ability to browse backwards in time through feeds, and an announcement blog. Many more things are still to come!
We have had a few problems with feed continuity - some articles from the arxiv have failed to show up, or have showed up late. We’re working on this, and things seem to be smoothing out.
Thanks to everyone who signed up, especially those who provided feedback - we have nearly 250 registered users!
