Fair do's impressive post, I liked your shorthand way of solving FODE, that will help a lot of people, so well done for that.
Just something to consider, if you used a bot to upvote your post sometimes it can work against you. For example people with heavy votes may not want to vote on a post that has 99 votes already, as some people look to gain SP, this may put them off. Secondly, the curation group don't like to upvote posts that have used bots, curie can give you a big ass upvote believe me, so I'd stay away from using bots and stick to good old faith in the community.
