What I'm doing is trying to follow and upvote members who upvote and follow me or who I can tell are actively reading and replying to other peoples blogs. I'm giving back to those who supported me early with 100% upvotes, but I know that I can't do that forever. When I get too many to repay or reward everyone I will probably start rationing my votes and try to return upvotes in kind to those who upvote me and at the same time search for others that are active and upvote them. At some point I will also likely clear my following list of those that are not actively posting on blogs and upvoting different people. They don't necessarily have to be posting on my blogs or voting on my posts, but I do want to follow and upvote the people that are active and giving to the community.
