pubsubhubbub support for externalfeed block

[Ruslan Kabalin]

As pubsubhubbub (http://code.google.com/p/pubsubhubbub/) becomes more and more popular (e.g. supported by google reader, blogger, wordpress) we might consider supporting it as well. The idea is that when the remote feed is using the publishing hub (that is a part of feed xml spec. now), the new post will cause the hub to feedback subscribers by touching the specified link with pre-defined parameter so that subscriber will be aware that the feed has been updated and reload it (as opposed to blind check of the feed each hour that we normally do). The subscriber php library (http://github.com/lxbarth/PuSHSubscriber) also available.

Hi Ruslan,

Is this a wishlist item you wish to still keep alive?

Cheers
