Most likely this is the same issue I ran into a few weeks ago. First, PubSubHubbub only sends the changes to a feed, not the whole feed, so you would only see a few updates at a time. Second, the hub is sensitive to even small changes such as the number of comments on a story if the feed contains that information, so it may seem like it's giving a lot of duplicate updates for a few items.

I'm testing out Google hub by subscribing to the TechCrunch feed, which does list "pubsubhubbub.appspot.com" as it's hub. I'm seeing something odd about the notifications I'm getting. There are missing articles, and a couple old articles are being sent again and again. Here is a list of the notifications I received listing the post titles in each one: 11-12 04:38PM: (first notification from the hub) title = "Facebook VP Leaves A Lover Letter For Apple", title = "Incsub Launches WP Plugins; App Store For WordPress Plugins", title = "Reddit Opens Its Homepage To Anyone Willing To Pay (Invites)", 11-12 04:44PM: title = "Myxer Delivers 10 Million Ringtones To iPhone Users", title = "Incsub Launches WP Plugins; App Store For WordPress Plugins", title = "Reddit Opens Its Homepage To Anyone Willing To Pay (Invites)", 11-12 04:54PM: title = "Facebook VP Leaves A Love Letter For Apple", title = "Incsub Launches WP Plugins; App Store For WordPress Plugins", title = "Reddit Opens Its Homepage To Anyone Willing To Pay (Invites)", 11-12 05:01PM: title = "Incsub Launches WP Plugins; App Store For WordPress Plugins", title = "Reddit Opens Its Homepage To Anyone Willing To Pay (Invites)", In comparison, here is the list of titles as I see them when I view the feed at (http://feeds.feedburner.com/TechCrunch) Facebook VP Leaves A Love Letter For Apple The ScamVille Lawsuit: Facebook, MySpace, Zynga And More Face Possible Class Action Suit Should Nintendo Fear The Apple Juggernaut?

Am I doing something wrong? Thanks, Waleed
