In the grand scheme of things, my 27 domains switched from GoDaddy won't change much from their company's perspective, but I will not continue to use them as a domain registrar because of this.
They sure HAVE to notice it. I've already transferred my domains and I'll make sure I won't buy any from GoDaddy again.
GoDaddy already has one of the scammiest UIs I've ever come across (with a possible exception of, maybe, MySpace) and the recent elephant killing was the last straw!
He might notice, but he's making so much money that I really doubt he cares.
Name.com's interface is a little confusing and NameCheap have great customer service!
