A pretty nice skeptical writeup on the Cosmic Variance (http://cosmicvariance.com/2008/04/21/guest-post-juan-collar-on-dark-matter-detection/) blog.
In short, it's a pretty cool result, but it's evidence of something interstellar rather than dark matter conclusively, and they need to make sure their experiment is rigorous and their detector isn't measuring the change of the earth's seasons. Otherwise, if this pans out, this could go down as the first experimental evidence for dark matter :)
There's all kinds of evidence for dark matter. There's just very little of it *directly* - it's called "dark" because all the evidence says that it has to be there, because we can see it's effects on the universe, but we can't see it.
I meant, like evidence for dark matter as weakly-interacting particles, rather than all the other wacky theories that don't involve matter: weird modifications to gravity, extra fundamental forces, and space-expansion strangeness and such.
Okay, I'll stop pretending I understand the subject now :D
