Tweet your new blogposts on Wordpress with Web Hooks/Hookpress

TweetingWithHookpress.py

# Python 2.5.2 powered by GAE

# Like a typical App Engine environment with req and resp objects.
# Make HTTP requests with: fetch (see App Engine documentation)

STATUS = "[infinity symbol goes here] " + req.get("post_title") + " " + req.get("post_url")

#This ensures that we don't tweet everytime the post is updated after the post is published
#Wordpress continues to call the publish_post hook even when published posts are simply updated
