It sounds like this guy wants to participate in StackOverflow just to be there rather than because he finds it a useful tool for his own work. I'm glad there are hurdles for people who are just there to "get a good rep" rather than there to support their real work. A (hopefully) more common workflow would look something like this: - a developer googles a problem, the StackOverflow answer floats to the top, and he not…
And as far as I'm concerned, gaming Hacker News to get karma is much more useful than gaming Stack Overflow. 500 karma is required to downvote, and it takes a long time to hit 500 karma.
Of course, now that I have the 500 I rarely downvote. I wish I would have known that earlier. :)
In my opinion, PG should adopt the Stack Overflow downvoting rule (you lose karma for downvoting), and lower the required threshold. It's hard to tell if downvoting is being used more for good than evil, but it's definitely used to express opinion more often than it should be.
