I am a frequent user and love the tool!
I have one feature request: I want to see how much VESTS a user makes on average per top-level post (not comments!). This would be a helpful analytics especially with the ranking. It would show the "consistency" of an author. This metric might only make sense if that user has written 5-20 articles already.

Also currently in the tool the post count seem to also includes comments. It might makes sense to have another column just for top level posts (articles/storys).
