Tracking it by section as proposed would help with that sort of deal, for cumulative, to see if people are valuing your input in debates / shoring up their side of the argument in true hunter-gatherer band democracy style, writing valued handbooks, constructing useful homebrew or helpfully answering peoples' questions.
Whether this is something we should be tracking about a person is another question, but we already have statistics by board so it would be pretty cool. Little complicated though.
And, obviously, if it's just by post it's pretty obvious what the post is about.
