Edit: Blizzard just did a Press Release: BATTLE.NET AND FACEBOOK INTEGRATION. "The first step in the integration will enable StarCraft® II: Wings of Liberty™ players to quickly add Blizzard gamers who are friends on Facebook to their Battle.net friend lists, facilitating their social gaming experience on the service."

Toutou Sidescroller

We've seen an awesome 2D sidescroller game video appear on our forums (thanks tordecybombo). It is looks really amazing (and really hardcore)! If you know where to download it and who is the author, please post a comment :)

Big Blue by TheKaymon

If you don't want to wait for the previous map to be available, TheKaymon made a sidescroller called Big Blue. The engine is done and works really well however it still lacks (alpha! alpha!) of content. Thanks for the commentaries.

Mapster Project Minigame by PinWorm45

You don't know what to do and want to participate to a common project with some other mapsters? PinWorm45 is organizing a Mini-Game type map, basically you just submit one game and it will be integrated along with all the others! If you are interested, just read the full description.

UI Leaderboard by Dest1nyCP

Are you making a map and need a leaderboard, check out the custom leaderboard Dest1nyCP made for you. You basically have to copy & paste the triggers and edit it slightly to fit your needs. When Battle.net publishing will be out, doing such libraries will be a lot more easier.
