Third party identity (OpenID and Connect). These things extend beyond Facebook. They are working really hard to work with other companies to make things connect. Getting users signed up really quickly, while getting useful information from them, is a main goal of these open identity platforms.
Three20 - An open source library for iPhone developers. This library makes it dead simple to develop iPhone stuff.
Tornado - High performance web server for Python on relatively cheap hardware. The goal is to create real-time applications on the back end. Keeping the connection open on the server. Brizzly uses this.
PubSubHubBub - The way publishers and subscribers will interact in the future. An open standard for making feeds real-time. Imagine a kid in the back seat saying, "Are we there yet? Are we there yet?". PSHB is like the driver of the car saying, "shut up, I'll tell you when we are there". It's a great way to get your content published everywhere faster. Google Reader is already implementing this.
OAuth 2.0 - The next version of the web's valet service. This next version will make OAuth tokens and exchanges much simpler. Right now it's kinda tricky.
Facebook is already the main destination that people visit on the web, even more so than Google. I am excited to see how these open standards are implemented. I really hope that Facebook can open it's walled garden as they gain trust of the whole web.
