I'm trying to force myself to do this instead of always jumping straight to hacking a prototype together, but I always hit the same roadblock: domain names. The whole point of doing early validation is to avoid wasting too much time on an idea without legs, and yet the domain feels like such an important part that I feel I need to find a "proper" one. But I hate looking for domains, so I tend to just go back to hacking instead... Anyone else have this problem? Do you spend a few days just looking for a decent domain? Or just decide it doesn't really matter and go with a throwaway you can change later?
