I tried using it but you had to install a firefox plugin. You couldn't simply give someone your address to type into a browser. You had to get them to install the plugin before they could use your URL. It might take off if it worked without the plugin.
It's an alternative DNS root so some type of plugin is required since browsers typically use ICANN's DNS system by default:

I've tried looking for popular sites that have a .bit presence and haven't found any yet.
Is there a search engine for it yet? I know a lot of names are taken but they sure don't have a site.
Or I have the plugin configured wrong but I don't think so. Easier plugins would be better too though.
I'm working on an idea for a .bit site actually that will drive interest/traffic to the namecoin idea.
I'm not sure how old this is or if any of the sites are still working now but there is a list of some sites using .bit domains here:
