Shadows' first post has an extremely valid point - it's the tradition of this site being called Eurobricks, and its prominence in the online Lego community, There are probably a significant number of American members nowadays but I doubt most people could get used to Ameribricks on a permanent basis considering all the ridiculous things said in the other thread.
EDIT: Also didn't buy the 'major changes' at all; for one it happened on April Fool's/extended a bit after, and I'm sure the EB staff wouldn't have toyed around as much as they did, which is basically the entire joke.
