No real work at all, people need to see that it can be fun to comment. We are making great strides in the number of comments going out, people need to see that comments are just as important as votes and post. I think that now that we are making strides in the comment department on post that soon we will reach a snowball effect and see the number of comments increase, as they have steadily over the course of this year, or so it seems to me.
