Another tip I only just learned is that until you have gained enough voting power to make a difference, voting with a herd of people for the highest paying posts returns a reward so minimal that when you are just starting out it is more profitable to save what voting power for people you can make a difference to and who will notice you for it. I like the way that some posters always have a little voting appreciation for those (non-spammers) who visit their posts. I also like to give upvotes for people who give curation on my comments.
