I've had domains at godaddy for longer than I can even remember. In that time I've never had an issue with them.
However, their actions made me want to leave. From stripping the Whois Guard off domains because someone called pretending to be a lawyer (with no notice to the domain owner) to Parsons latest blog posts talking about how torture at guantanamo is a good thing at the top of godaddy.com, to the ridiculous TV commercials it all left a bad taste in my mouth. Hey, I like tits as much as the next guy, but what exactly are they trying to say with the pandering silicon bimbos?
I started moving to namecheap and have had no problems.
I just looked at name.com and it doesn't appear to have a reseller API. FAIL. I'm in the process of using namecheap's API to automate my domain registration through the administrative dashboard I'm writing. If I have to go to name.com's site to manage my domains, that's a non starter.
