And that's fine, because OpenDNS doesn't fit in with how you want your DNS resolver to operate. Again, it's a choice you have to make to switch to it, so you're fine to continue using whatever resolver you choose.
However, if you're like me and you enjoy the features that OpenDNS provides, then the choice to switch is easily made. If I would like to use OpenDNS for it's speed and still retain NXDOMAIN support, there is the option for me to do so (And admittedly, it's in an account section that should be more forward-facing). But I understand what the defaults are because I'm making the active choice. Don't insinuate that they hide these things away. NXDOMAINs are something that only advanced users would care about anyways, and you have to have a certain level of geekness to want to switch DNS resolvers anyways. So, give your fellow smarty-pants some credit!
