Tornado is an open source version of the scalable, non-blocking web server and tools that power FriendFeed. The FriendFeed application is written using a web framework that looks a bit like web.py or Google's webapp, but with additional tools and optimizations to take advantage of the underlying non-blocking infrastructure.
Runt.ly is the easiest way to create short blog-style posts to share over Twitter and other micro-blogs like FriendFeed, Yammer or Plurk. Runt.ly posts can include linked photos, embedded videos and more.
