I've participated in the sci-fi beta and my impression is that there were more votes (up & down) per question (and possibly per user) than here.

(If that is the case, perhaps there are more questions per user.)

But I don't have any data to know if my feeling is correct. The Area 51 data doesn't publish that.

Does anyone know how we're doing, relative to other betas, on the amount of votes?

I'm asking based on my assumption that voting is one of the engines to make a beta a success.
