"Whichever host you decide to sign up with, make sure their servers are in the USA, even if you
happen to live in Outer Mongolia. 90% of your potential customers live in the USA, and hopefully
they'll be accessing your site more than you will."
If you have a .com domain name, but your server is in Outer Mongolia, and is fairly powerful, does this advice still apply? What exactly are the reasons a US based server is better if you want American business? I'm guessing that maybe the site will load faster for Americans - is this true, even if you have a powerful server in Mongolia? How much faster would it load, and also, is there any place you can go to check how fast the site would load 'FOR AN AMERICAN'?
