Tangentially related, out of curiosity: Are all or perhaps only specific comments limited to a maximum of 75 points, or is it simply a coincidence that mine have never seemed to get more upvotes beyond that score?

Funnily a comment I posted yesterday just passed the 75 points, so it appears that either there is no cap or that it was lifted.
