Jesse claims the answer is yes.
This is a test to find out for myself.
Update: It worked! If your blog is PubSubHubbub enabled any new posts will show up in Google Reader immediately instead of taking the usual 20-30 minutes. Now you have more incentive than ever to get PubSubHubbub support on your blog!


I had an error,
"
Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /nfs/c03/h01/mnt/49370/domains/oonwoye.com/html/blog/wp-content/plugins/pubsubhubbub/publisher.php on line 10"
Which version of PHP are you using? My plugin requires PHP 5.0 or better. I've seen that error a few times now and every time it's due to someone using an old version of PHP.
Thank you for the wonderful plugin! It works instantly when posting manually but I noticed that when I schedule a post, it doesn't seem to be pushing the update out right away.
