Desire Path Highlighting

I've written about desire paths a bunch of times in the past. They're those extra trodden lines between two points that, despite not being paved, are clearly the most used way to get from point a to point b. Anyway, looks like Huffington Post has taken the idea of desire paths and built a little site around it. The gist is that they record every time someone highlights a passage on the site and then when something breaks a threshold it makes it to HuffPost Highlights. The actual results on the page are a bit of a mixed bag, as quotes out of context can be a bit odd, but generally it's a really neat idea and experiment (it's on the labs section of the site). Poynter has a nice explanation.
