I'm glad you mention this because that was the basically the motivation for me to build this tool in the first place. I was selecting a DNS host for the startup I was at and was wondering: "what DNS host do all my friends use?". I found myself doing a lot of dig commands, so I wrote what became domain-profiler.

I don't think you should spend a lot of time selecting hosting, but I do think you should put in a little bit of research into what you pick. It really sucks when your website is unavailable for an hour due to issues with your DNS provider - especially when your TTL's are set to an hour.
