Well, the person in question identified herself as a lesbian, so she probably didn't use that exact wording in her profile.

I could be wrong.

It's no more odd than mentioning hobbies and interests that aren't related to gaming. I mean that's the purpose of profiles isn't it? Talking about the things that distinguish you from everyone else?

This question often comes up on forums like Gamedev.net, and the answer is always the same. Nobody wants to buy game ideas, from you or anyone else. Ideas are a dime a dozen, and there is too much legal difficulty involved in even looking at someones idea. Developers would much rather work on their own ideas (of which they have many) than take on someone else's.
