Seeing as I ran the 98+ BoTM until now, I guess I should answer this one.
Well ...
Last year we had around 14 entries on average, with 50-55 votes every 2 months. Most winners had a single-digit vote count.
The BoTY ended up getting a similar amount of votes. There's just not enough interest.
Those who are interested want to push for monthly events, but we just don't have enough 98+ bikes for that here on RB.
A few months ago, I did talk to John about this very subject. We decided to wait a bit while we figured out how to motivate people to vote. I guess we simply haven't got it figured out yet.
