Doesn’t matter if you care about SOPA or not (you should) because Go Daddy is a pretty crappy registrar. I use [Dynadot](https://www.dynadot.com/) (use referral code: 6J7g8FT6q6p6S7F and I get a kick back), but I hear [NameCheap](http://www.namecheap.com/) is popular these days.
Update: GoDaddy has [withdrawn support of SOPA](http://thenextweb.com/insider/2011/12/23/go-daddy-chokes-on-the-internets-vitriol-pulls-support-for-sopa/). Still don’t use it.
