Many thanks, and good tip on the dev mode — I didn’t realize it was there. Crusade on!
Suddenly our feed was accepted by MyYahoo, too.
Perhaps Yahoo takes its time recognizing a feed, something like DNS proliferation? Might be nice if Yahoo documented it a little better.
For what it’s worth, I don’t think it’s Dreamhost; we’re building a brand new feed on a totally private corporate server and running into the same problem: adds to Google, validates at W3, chokes MyYahoo.
akabin, it looks like you got the rss2 php feed to work on MyYahoo (at least, I was able to subscribe to it); I’ll pay *you* if you can tell me what you did there!
