I mean I got the point of what the author is referencing and agree with some of his points about the Valley being an echo chamber. However it can not be considered a Silicon Valley darling unless one wants to admit that success (I think that Groupon is, but I will accept that many don't think so) is somehow only associated with the area. I guess that is why I felt the need to point out that Groupon is not based in SF.
Edit: clarifying success reference to be clear that I mean I think that Groupon is a success and not that I think that success must be associated with SF
