I dont know but it's stupid
Yes
Simple; you have to use your email instead Facebook login is optional.
yes,of course
You do now. When I first joined, there was no requirement to have a facebook account. This has since been changed so that all new users must sign up with their facebook ID.
You would have to have to have done it a while ago, but now you can't. Maybe they will change it back some day.Doubtful that such a day will come..At one time, you could, but you no longer can. Clicking "Sign up" brings up a page which uses Facebook to authorize your usage of this site.If you do not have a Facebook account, the only other thing you can do on the page you get when clicking sign up is to join Facebook.I don't know if that is what the Answers.com originators intended, but that is a change that their programmers have made.Because of that, you can no longer join answers unless/until you have a Facebook account.Facebook is becoming a de-facto single-sign-on mechanism.
Ask Mark Zuckerberg, but I don't think he'll tell. I believe he wants to force you into Facebook, where your life is without privacy any more, whether you like it or not. Personally I have forgone joining.
No, Answers does not post the questions on Facebook.
No, they aren't.
You can post an answer from answers.com to Facebook by copying and pasting it. There is no Facebook or any other social media share button available to users.
No, a Facebook account is not required. You can sign up with either Facebook, Twitter or your email address.
Without clarifying what you are joining, it is not clear whether or not you need a Facebook account to do so. For example, you do not need a Facebook account to join in a game of baseball, you just show up and ask the people there. However, you need a Facebook account to join WikiAnswers.
