Facemelt

Facemelt makes integrating Facebook Connect and Facebook Open Graph functionality (publishing to the timeline, etc) with Drupal 7 easier. Easier than what? I don't know, I didn't do an extensive amount of research.

Facebook Connect

Facemelt provides a variety of different options for controlling the login/connect user flow. No need to understand anything about PHP or module development to get this sucker up and running however you might need.

Facebook Open Graph

Facemelt provides admin interface options as well as module hooks to make it relatively easy to get your Drupal site publishing to the timelines of your unsuspecting users. Good thing? Bad thing? Life is too vast and mysterious to worry about that.

It's triple cached

...using the cache_money module. cache_money caches less-dynamic content using drupal_static(), which is backed by Drupal's cache_get()/set() interface. More dynamic content (primarily stuff that varies per-user) is cached in the user's session store. Also, it uses anonymous functions, which almost makes you feel like you're programming node.js. Almost. I mean, when's the last time you were able to use lambdas for cache invalidation instead of boring old expiry timestamps?

GitHub is recommended

I think most people would agree that it's less of a pain to push frequent code updates to GitHub, so if you want to make absolutely sure that you have the most recent release, you might wanna git clone git://github.com/brynbellomy/facemelt.git.
