I think 40 votes would make it harder to run a bot/self vote but there are many bots that already vote 40+ per day i.e. not at full weight.

The extra decimal in the UI I love the idea of though. I remember when I started I had very few votes and those I did were of 2 cents or less. These rewards are not even paid out to minnows. If minimum to get a rewards was 0.001 SBD or less it would encourage people just starting. Not with money, just encouragement that they are getting something for their efforts as opposed to nothing.
