DotBlu, a social network/community for online gaming, has picked up $2 million in a first round, peHUB says, citing a regulatory filing. Maples Investments and DE Shaw participated in the round. DotBlu members can play casual games, take quizzes and vote in polls using BluBucks, the site’s virtual currency. BluBucks can be used to customize a player’s avatar and create new games and competitions.

The SF-based company launched in stealth last year as an online betting service called BluBet. It was backed by $225K in seed funding from YouTube co-founder Jawed Karim and Flixter CEO Joe Greenstein, among others, per TechCrunch.
