I used to just post once a day as well as I didn't want to burn through the Voting power of those that have me on auto vote but lately most people that have me on it are saying its okay to post twice a day and I used to self vote so that is 4% already off my voting power.
With me not self- voting anymore this gives me more votes to give to people. It is a personal preference that I want a value to show when I upvote a comment because I want to reward people.
