Keyword domains with funny extensions?
 

I bought one of those new domains with a funny extension, www.spanking.vg (bahamas or something, I forgot). Naturally I am not planning to promote that, but just send the traffic to a spanking site. Is it worth building a few links around it though - will google give me the same huge credit for the keyword like they do for .com or is the keyword useless otherwise. I don't really care, $15 investment, just wondering if anyone knows.
