Just to be clear, PG probably doesn't monitor these things because it would be a little underhanded. At the same time, these metrics might be useful in some way when deciding whether to fund a person or not.
1.) noprocrast habits -- whether a user uses it, how long they set it for, and whether they used to override often when that option was available.
2.) The user's upvote/downvote ratio on his own comments.
3.) Most visited sites, by monitoring clicked links.
4.) Most upvoted user(s).
