I really like the post "Vote early, vote often". When I look at the all-time voting statistics, it seems like our experienced users, as a group, don't vote much (between a vote or two per day of membership, maybe less). Is this level of participation normal? If not, how can we encourage people to vote?
The thing that's really holding me back is the relatively low rate of questions being asked, and I think the thing keeping vote totals low overall is the relative smallness of the community. The monthly voting statistics for physics and computational science look similar, but the scicomp.SE community is much smaller, which means we have fewer frequent voters, and fewer voters period.
Ultimately, I think we just need to attract more people to the site.
