Back in June Blizzard showed off the beta stages of their Starcraft II community forum, The Arcade, and the latest patch makes it official. In case you missed the fuss over this, it's a pretty major event for the SC2 community because it provides a new platform for sharing content created in the game's hefty editor. Custom games will now be easier to track, even before they are released (assuming the author updates and so forth) and it should make it easier for folks to promote their creations to the overall community. As closed a system as Blizzard games are right now, this seems like a large and positive step in the direct of acknowledging that the PC is just as much about making stuff as it is about playing stuff.
And in case you were thinking "that inevitably means DOTA in Starcraft II, right?" Blizzard are already working on it, as announced last year. "Soonish", indeed.
