I fail to see how. I had an opinion about the thread, and in addition, an opinion about that opinion: that it was worth expressing. So I did. Others may disagree with either of those opinions (for example you), but they do not choose my actions. I do. What is the score in this hypothetical game? (It isn't the karma rating of Multiheaded's post.)
If you make your opinion more prominent by expressing it in a post instead of an upvote, you encourage others to do the same, thus lesswrong has more non-content posts and nothing much is accomplished by anyone. Since so far this thread has two posts of the type I describe, I guess the score is 1-1.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Of course, for "every Monday", the last one should have been dated July 22-28. *cough*
