My goodness, demands? Well, I can say exactly when I found it: it was back when I was posting about the date of Someplace Else and I told Terrapin to go look at the blog post from the previous April Fool's day. I looked myself and stumbled across this. The how still has a bit of mystery to it. It was through the fake google ads on joke page 3, the links in them went to the index directory, though then and now they usually point to that same page (joke page 3). Not sure exactly what's going on there, Adam didn't seem to be aware of that approach.
I hope, having seen it, you can understand why I didn't say anything at the time? (the "our little secret" bit)
Actually I didn't think it was Earth when I first saw it. (I'm thinking Rayleigh scattering (blue sky) and cloud formation would be common to any habitable world??) I actually thought it supported my (already postulated) idea that Minerva was an alien of some sort. But that idea seems to be shot now, now that we know (?) that she is or was human.
But, it did I suppose influence my suggestion that the world on the other side of the portal is Earth in the future. If Minerva is/was human, and this place was her home ("once, maybe") then, well, there you go. Not that I'm 100% convinced, I'm sure there are numerous ways to have this not be earth now or anytime.
btw, in case it wasn't already clear, this is the low probability page five

and I'm pretty sure what Adam was referring to here: (which I intentionally plagiarized above)
