I've been trying out DailyBooth for about a month now. I like it. As a common user, and not a celebrity, I find dailybooth more valuable than twitter. I guess "a picture is worth a thousand words."
I'd say a picture is worth a thousand words for person perception and impression formation. It takes a dozen tweets to figure out if you like someone, but only a few milliseconds of seeing his or her face. DailyBooth leverages that very well for dedicated community interaction.
