Let's hope it is not something that will let 10,000 people down, like "a new app".. If you are gathering 10,000 people to see something, it better be something more than a rabbit out of a hat, or you will have 10,000 angry people.
Not that I'm a geography expert, but I see what you mean?
Is this a country/region specific announcement?
When I used to have FaceBook, people--mostly from Indonesia--would take any post (even if it were about CANCER awareness) as an opportunity to comment with their PIN in hopes that they will "meet new people" or something.
It was either that, or people talking about how much better their iPhone is since they decided to ditch their BlackBerry - and I'm not sure why they still "LIKE" RIM or BlackBerry on FaceBook, but these things happen...
I imagine us non-FaceBookers will find out via CrackBerry what it is though!
