Never saw o porn related website using .org Not much in value, reg fee maybe, but it all depends what you would do with it. Good luck!
I'm curious as to why people keep saying this in domain valuations. Of course if a domain is developed the value is endless. facebook, bebo, ebay, myspace, twitter, etc are all nonsense words but of course are worth a fortune. The developed value of skdjfghbdfgjkdbfh.com is also endless.....
Facebook has no meaning - its two random english words that mean nothing put together. Without a website on it myspace.com is worth under $1k.
I don't mean developed into an amazing website. I mean a decent, half *** $100 design and it's value shoots up. I said it because it's true. Some domains DO have limits. Without a uber amazing idea, like Facebook, or loads of money, like other projects that I can't think of off the top of my head, every domain has it's limit.
