copyright assignment - why ?
While ODbL has a page describing why it was chosen instead of CC-BY-SA, the Contributor Terms have one other glaring difference for which reasons are nowhere mentioned (at least not where I could find it).
It would be good to explain why they require copyright assignment, while before they didn't, and why is it better than alternative of, say, each contributor dual-licensing him(/her)self under both ODbL and CC-BY-SA.
One good piece about advantages and problems with copyright assignment could be found here: http://people.gnome.org/~michael/blog/copyright-assignment.html
