This is going to be a fairly short diary since it's my first diary. One of my interests is geography, and in my opinion, our maps of the world should be centered around the Pacific Ocean, specifically around the 148th meridian East.

Let's jump below the fold.
First, here's a Pacific-centered map.
In my opinion, world maps should be centered around the Pacific because, for starters, there is a huge gap between the Old World and New World on the Atlantic but only the shallow region of Beringia on the Pacific. Far eastern Russia and Alaska are on the same tectonic plate. Maps of Pangaea are centered on the land because it was all clustered together, so since all land on Earth except Antarctica is (roughly) connected, our maps logically should be centered on our "Pangaea".
Second, the central Atlantic is basically devoid of islands except for Greenland, less than half of which would be sorted to the Eurasian side of a 148th meridian-centered map. OTOH, unambiguously Old World societies exist throughout the Pacific.
Third, human migrations are better shown on the Pacific map. For only the past 1000 years has the Atlantic (except, of course, for the Mediterranean and North seas) been important. Humans almost certainly entered the New World by a west-to-east route, either just south of Beringia or on it.
One final note- although South-up maps are interesting, there's more land in the Northern Hemisphere, so our maps should still be North-up.
