Chiming in yet again to agree that social media presence is extremely important for any indie studio to be successful, even if it's just having a personal Tumblr or Twitter account people can follow where you also occasionally post news about the game. Aside from letting people find your work and giving fans a place they can interact with you, it makes the studio look more legit.
And you definitely don't have to update people on the game when you post! You can talk about other people's games, write about general developer stuff, drop little snippets about the characters, whatever.
