I know that my participation is down based on my recent move. Last year I was able to moderate one of the contests and took it to heart based or historical research of days gone by.
In putting forth the effort to drive numbers up for a new contest I graciously (and ungraciously) inserted a lot of comments and banter about MY (lol) contest everywhere I could And then some.
It was fun, frustrated a few people, but we had great participation and a large turnout for the vote as well as other contests pushing back in a good natured way.
I have a note to make some vendor orders but did have to dig around to find the discount thread.
