I want something that mimics or implements the existing program. Why reinvent this wheel? If it already does not feature, %positive will be an interesting feature. A very interesting extension would be to see how %karma and karma correlates with written content. For anyone machinelearning afficionados who wants to experiment with these ideas, I volunteer an unrestricted (for either/or commercial or noncommercial) use of my comments and posts. If you are interested in using my LessWrong account as a training data set, feel free to use my reddit account (/r/fruitheart) for outgroup comparison.
