Since I am apparently in the minority on this one here's my two cents.

First, there's a finite amount of actual news here. When there's a new revelation, I want to see it. "More NSA news" sounds to me like exactly what I don't want: every programmer's personal outrage, every major news outlet's take on the latest revelation, and so forth. I don't want to see every story's comments degenerate into NSA discussion. Having a story about the NSA on the front page in perpetuity puts it in the back of everyone's mind.

The level of discourse has, mostly, been high and valuable, but I worry that we're inviting in people who only want to talk about politics, and that's going to drive me and every other technically-minded person with limited energy away.
