Votes peaked at 488 on January 6th after this post from Jon Ericson
How can we increase the number of eligible voters?
General Stats
Our last peak was 288 votes on March 17th.
So that's a net loss of 200 votes per day.
Thoughts
If you look at the site analytic the traffic increased with the additional voting and we picked up about 75 users with over 200 rep in that time period from the beginning of January. It directly links voting to increased user base and traffic which ultimately fuels questions which, as of right now are 13.1 per day.
I've been struggling a bit because of a drop off of answering of questions, this is just the last few days, and have tried to fill the gap.
We need more mid level users and truly believe the data supports voting as the primary vehicle to rectify this issue.
Interested in hearing peoples thoughts on this.
