Keeping tech blog comments sane

Here's my question: Is it even possible to keep the comments on tech blog articles humane or will it always descend into meaningless crap-flinging? It seems to happen to every tech blog at some point, at which point a new tech blog will be started and the more sane out of the old site's crowd will have a safe haven for a while.

I like the Verge more than any other tech blog I've visited so far (except maybe Ars Technica, which is more in-depth and a bit of a different niche) and really do not want to see it sink into the darkness of inane trolling and platform holy wars.
