Thanks for all of your help and clear explanations!
FeedBurner seems to auto-add a pubsubhubbub link to all feeds even if the underlying one would rather rely on the polling model. If you look at the differences in XML between the original feed (http://jmillerinc.com/newsyc100.xml
) and the feedburner one (http://feeds
) you can see that feedburner automatically adds a <atom10:link xmlns:atom10="http://www.w3.org/2005/Atom
" rel="hub" href="http://pubsubhubbub.appspot.com/
" />. Which my feed reader (theoldreader) then respects and waits for the notification and only refreshes every 6 or so hours. I assume this is probably happening with other burned feeds as well.
It feels like a feedburner is the one that is making the mis-step in the chain (or my expectation that a feed shouldn't have to implement notifications and should be allowed to rely on polling). You guys know of a different group/list that I can post this to for feedburner?
