The way this sounds is that you are more concerned about politics as in people who take party positions and may feel excluded as a group when the majority of the community takes a different position. This is a slightly different issue i.e. party politics, and I think it is fine/a good thing, but it is also important to distinguish the two. This should essentially be under the same umbrella as personal attacks, as they are essentially the same thing.
I see this great move as a way of the community lifting its head out of a sandy quagmire to glance at the shining beacon, the vision on the hill, the where we want to be, unsullied by political nausea. Sure, in a week we can get back into the grim reality, the tech-noir crapsack future, but perhaps for one week we can focus on a positive future and its soaring aspirations. Go Dang!
Technology and politics go hand in hand, unless we'd like to head back into the dark ages.
EDIT: I'm not hear to offend or persuade with politics talk. I'm here to provide or obtain new perspectives and understanding. If I want an echo chamber that reinforces my perspectives and beliefs, I can head back to Facebook.
EDIT: Which HN is totally within its right to do.
