What do you guys think anti-government.com would be worth?

nothing. its got a hyphen and has no real commercial value.

One of the benchmarks to tell the value of a domain name is to check if that string before the dot (i.e. "anti-government" in this case) is also registered with other TLDs (e.g. .net, .org, etc).

Right now i'd say its worth the registration price unless you develop the site and attract some visitors to it.. it's got great potential though. ;)

not much, you cant sell it to government right? :) and I cant think of idea how could it be turned into e-commerce site

Looks like a great way to get on a list though.

"The List"
right? Maybe you will be labeled a terrorist and paralleled to the "Axis of Evil." .... well... its not THAT unbelievable anymore.. :P
