This comes up almost every time someone does what I just did. You're right about the Voting-Based Social Media Site Psychology of it, but I think we've covered it enough that it doesn't need to be said.

I do regret adding that to the end. I really didn't mean to influence the votes. Now, of course, I can't remove it without eliminating the context for our discussion.

Edit for more meta: Apparently I am now That Guy In The Thread Whose Comments Are All Downvoted Regardless of Contribution to the Discussion. I am also That Guy Who Left A Stupid Reddit-Style Comment, That Guy Who Is Spending To Much Time in the Thread, and That Guy Who Thinks Hacker News is Going Downhill. Time for a sandwich.
