Nice post, I am also a developer working on http://steemwhales.com since 2 weeks now. Feel free to look at my latests posts for more information about it.
You are also missing http://steemstats.com that I use everyday.
Also this post https://steemit.com/powertobots/@curator/curator-bot-chrome-extension-available-open-source-code-on-github is another upvote bot with the code on github.
Thank you for more data :) I've added you and your project.
