Competing as in dilution of search -- possible. .xxx, .sex, and .porn are all of the same genre (pornography connotations).

The idea of the new gTLDs is to associate the domain name with the genre of the content or in some cases the maker of the content or trademark holder e.g.; .ibm, .google, .cocacola, etc.

What is a better descriptive name of content?
trailertrash.info or trailertrash.sex?

If trailertrash.info is about life in the trailer park and trailertrash.sex is about getting laid in the trailer park; Which domain should be more relevant for the search 'trailer park orgies'?
