So how did the Americans here become Evertonians?
Decided to pick an EPL team after World Cup 2010 since I love soccer (been watching the US national team and the Turkish national team for ages). Started with the teams I knew (aka, wasn't going to pick Stoke City) and/or teams that had American ties, and watched games for a couple of months. Everton was included on that list because I knew Tim Howard was their GK, and LD played there.
1) Couldn't be a bandwagoner - so no Man U, Chelsea or Man City.
2) That left me with: Fulham, Aston Villa, Spurs, Liverpool (blegh), Arsenal and Everton.
3) Watched the games and Everton's personality just spoke to me. Hard working with some flair, great fans, some great players, great manager, Tim Howard, and LD was rumored to come back. Plus, I lurked on this website and saw some great posts and great people.
So, became and Evertonian in 2010 and never have looked back. Even with money troubles.
One thing that annoys the crap out of me: Everton's lack of marketing in the US. Drives me nuts.
EDIT: And I'm a fellow Californian.
