Did you see this April's Fool Day comic on xkcd, with an interactivly growing dog: "The dog gains a pound for every $10 donated to the Wikimedia Foundation via this link."
Is this real? How can it tell how much has been donated to WMF through this comic? I see that there is a special campaign reference in the donation link but how can it fetch the amount?
Has there been any cooperation / negotiation between Randall Munroe and the WMF beforehand?
