PubSubHubBub Publisher
Previously, I had been pushing pings to blo.gs, blogrolling, technorati, and weblogs. I removed all of these, and added pubsubhubbub.appspot.com. This involved two steps.
Adding the following to my feed:
<link rel="hub" href="http://pubsubhubbub.appspot.com/"/>
And, adding the following to my publishing flow (based on pubsubhubbub_publish.py):
#!/usr/bin/python
import urllib, urllib2
hub = 'http://pubsubhubbub.appspot.com/'
feed = 'http://intertwingly.net/blog/index.atom'
try:
data = urllib.urlencode((('hub.mode','publish'), ('hub.url',feed)))
response = urllib2.urlopen(hub, data)
except urllib2.HTTPError, e:
if not hasattr(e, 'code') or e.code != 204: raise
