Can't wait for pubsubhubbub to go mainstream... Imagine the pushing around once everybody supports it.
Right now there's only one plugin I can find for Wordpress.
Once other CMSes support it, we'll be pushing feeds like crazy.
And I'm shocked that Google Reader picks up feeds like me picking myself up and out of bed every day for the past two months.
Slob. Lazy. That's what I am.
Note: FB just picked up my FIRST post! "22 seconds ago" says the time of receipt.
