First, the basic math: the server officially was up and running at MSU on the 9th. Average daily number of votes before the switch: 2219 Average number since: 3651.
Someone can correct me if I'm wrong, but I believe I removed the vote dump bonus on March 20th. We didn't post it as a News item until the 23rd (though we did have it in the room topic.) Average # of votes from March 1st to the 22nd: 4132. Average # of votes from the 23rd to today: 3769. And if you remove April 1 (an outlier - most people who visit the site that day don't vote or post writeups), that average goes up to 3908. Less than a 5% decline. At best.
Sorry, very few people are no longer voting because of the no vote bonus. Many more people are voting because the site is so much faster.
Note to Level 3 users: if you cannot figure out how to spend 20 votes on this site in one day, you are not doing it right.
Note to Level 2 users: if you cannot figure out how to spend 10 votes on this site in one day, why did you become Level 2 in the first place? It's not like you have time for this site as it is.
