Tim Bray’s statistics show a small but growing number of people prefer his Atom feed over his RSS 2.0 feed.
As my weblog supports more feed formats, my data is a bit more spread out. About 45% are subscribed to my RSS 0.91 feed, 10% to my RSS 1.0 feed, and the remainder are pretty evenly split between RSS 2.0 and Atom 1.0. The other feed formats get trace amounts.
This leads me to wonder how many aggregators actually support RSS 0.91 correctly, as that is the one feed format that is unambiguously <plaintext> from top to bottom.
Last year, I removed all of my redundant comment feeds. Perhaps it is time to weed out my primary feeds too.
