Ok, I just took a look at the site and I have to say, this is going to soar, seriously. I'll give you a spin from someone who might just have a little more experience in this than some do here n this thread:
1) Some MAY find offense to it, but those that do are most likely going to be ones that are guilty of some of those things I see here... and when you get that, know I said so. ;)
2) This is going to be wildly popular for both men and women, I'd bet, seriously.... guys trying to gather all the info and girls trying to find out what info you are giving the guys... and in saying that, they will try new things and you have ever growing content for this project just in that alone.
3) These things will be very valuable in the "REAL WORLD" and not only online, they can learn online and actually use it in their real lives in real places other than online, therefore giving more reasons to actually go and interact with the world again, maybe?
4) It is a physical thing... it's going to make some places very rich with a cluster of people running out to test this out.. so businesses may benefit from this site as well.
and last but not least:
5) I offer one suggestion, you should put a feedback area, there may be one, but I didn't see it. So they can report back THEIR findings and THEIR experiences with you and others like them running out to try this on for ... umm.... size? lol
All in all, I give this a huge thumbs up and I think you may have just hit something that has been looked for for a very long time. A REAL place like this, not just a movie.
