I know, LTARs, that you guys didn't start the post, but my comments apply to the whole discussion. The ideas I listed were the ones I recall seeing suggested most often.

The country loyalty is rather silly. There are plenty of good people all over (and, granted, some tools), but the remark someone made about the only real difference being the icons rings true.
