Opportunity cost would be nice to know too. I'd like to know how many people read my post and then voted for somebody else. ;) Seriously, a post that gets 10 reads and 10 votes may be much better than a post with 1,000,000 reads and 100 votes. Knowing this could help solve Warnock's dilemma.
That said, perlmonks works perfectly for the community. Conversations are on-topic. Flames and attacks are rare. Wrong answers are quickly corrected. Changes at this point will only help authors seeking meta-enlightenment.
