-'''To make the explanation of the title text more complete:''' The statement that ''topologists now believe it's actually their outer edge'' seems to allude to a concept similar to that behind Wonko the Sane's house in ''So Long And Thanks For All The Fish'' by Douglas Adams. Said house has its outer walls on the inside, declaring the rest of the world to be inside an asylum for its own safety. By challenging common notions about what's outside and inside by a radical change of perspective Wonko the Sane effectively constructed a building with the floor area of almost the entire Earth's surface. Similarly, this map projection seems to declare that you can see geographical centre of the USA as their outer edge, if you just change your perspective a little. The map projections we're familiar with may have a great influence on our perspective on the world (cf. Mercator vs. Gall-Peters projections, Winkel-Triple projection centred on China, Australian world map with South on top, and so on), a topic that I believe Randall has always been fond of exploring both in a parodistic way or playing it straight.

+EDIT: I asked about a possible addition, which I've now added, hopefully doing it right this time. To avoid unnecessary clutter I deleted that comment (all its content is up in the explanation and those parts that don't survive scrutiny aren't worth keeping), but left the answer, as it contains good advice for relative noobs like me.
