I don't think it is an accurate reflection of the community. It certainly doesn't reflect my experience with the LW communities in Toronto and Waterloo.

It is also not an accurate depiction of the community in London or Edinburgh (UK). However, I think it is pretty close to exactly what I would expect a tabloid summary of the Berkeley community to look like, based on my personal experience. The communities in Berkeley and NY really are massively different in kind to those pretty much anywhere else in the world (again, from personal experience).

And, as Kevin says, it is remarkably nice - they could have used exactly the same content to write a much more damning piece.
