To me, the real reason for posting an intro is to help protect the board from spammers or people who are only here to sell their products. Usually these types won't take the time to fill out an intro and move on. I know that I hate reading a first time post from a new member and finding the post to be nothing more than a sales ad. Intros are the easiest way to filter "unwanteds" out but not the only way.
As far as posting an intro, they're only as truthful as the keyboard and it's operator wants it to be. Why should a person have to let everyone know where they live or what their other interests are. The main point is they're here, they're contributing to their hobby and they're learning about others with the same interests. Most of the members do actually end up posting where they're from and their other interests anyway. But for those who don't, oh well. Just cause we don't know where they're from or that they like long lonely walks on the beach in the middle of December, doesn't mean that they don't have something to offer the board.
Alot of times a very interesting topic gets sidetracked by someone worrying wehether or not the person has posted an intro. Give it a rest, you're not looking for a prom date! If a new member wants to do an intro, fine. If not, fine. If they're here to be a part of our hobby, that's what counts. OOhs and ahhs are just as appreciated as long winded babble about the contents of the topic!
For those members who are selling something, wouldn't they just post their address anyway? I know that if I was selling something internationally, I'd make sure that I posted the price and where i live so thast potential buyers could figure the total price before purchase. And just because they live in Hayfield, South Washigton doesn't mean that's where the product is being shipped from. Also, isn't there a special section for selling/trading?
After all my babble the bottomline is ... you don't need to know where I live, what my favorite color is or who's my favorite superhero. All you need to know is, that I enjoy what this board is about.
Just my opinion,
