That guide is USER supported with USER content. In fact there are well over 1,000 personal reviews on it, so how can you blame one person? Why haven't YOU contributed something useful to the guide, esp. if you think it's not correct? So if it's not up to your standard, it's YOUR fault, because YOU should be contributing, and not complaining about it. Got it? Anyone can submit a review, and apparently only 45 are popular enough to have gotten one. BTW, there are no longer 300 coffeeshops in Amsterdam, so your info is OUT OF DATE.
