Oh I get it.
Hmm, sounds decent enough.
I think that if Greg wanted to learn statistics about his users it'd be good.
What I would suggest greg, is that it be set up so once someone comes to the site, they MUST vote on the poll to access the site.
That way every user will eventually have to vote on it.
And once a huge percentage of them answer, it's closed. And of course once someone answers the site is open until the next poll.
I being someone who likes to learn statistics, it sounds cool too.
You could learn demographics about your users, and post the results in a demographic section.
We could learn religious systems, locals, ages, genders, etc...
And because it would be mandatory, it'd be much more scientific!
What say you greg?
