Web Browser Compatability

When doing a website, do you think it's right to be code for only certain browser (ie the most used browsers like Firefox & IE (latest ver)) and to just say to other users of browsers like Safari, IE 5 , "sorry you cant use this site"

Okay... but you didn't state anything aside from common knowledge. I don't get it. Are you the guy that usually makes new threads stating the painfully obvious or something?
