We now know that this site will be launched out of beta in about a week, B"H, under the name Mi Yodeya. A close-to-final draft of the design should be posted here on meta soon.
Please put exactly one name idea, along with why you like it, in each answer. Even minor variations on an idea should each get one answer. That way, it will be easier to determine through voting which name the community likes best.
Feel free to re-use names proposed in the previous discussion, whether you proposed them or not. If you use someone else's idea, it'd be nice to give credit, of course.
