I have never heard of Glancee before today. Going to their announcement page tells me nothing about what exactly did, or do now, except a generic blurb about bringing people together.
The TechCrunch article, on the other hand, gives me information about exactly what these guys used to do, and who the remaining competitors are, which is a pretty big deal.
To concur with Yuri, I clicked on the article here hoping to figure out what Glancee is, since I'd also never heard of them. Their post tells me nothing, except that they're going to Facebook, and other positive rhetoric.
99 times out of 100, I'd probably be in line to rally behind you to get the original article up above the rehashed news article, but in this particular case, TC added value, to the degree that the original story was no longer useless, and deserves to be the higher rated article.
I absolutely hate reading TechCrunch. This is how much I hate reading TechCrunch: I actually read Hacker News through my own customized filter site (http://hacker-newspaper.gilesb.com/), and one of the biggest benefits is that I hard-coded a TechCrunch ban (along with several other sites I don't ever want to read).
However, I have to say, this logic is completely sound. I hit this Glancee blog link and was left wondering A) what on earth these people even do and B) why people on HN are talking about it in the first place. For once, I wish I'd seen the TechCrunch link!
