OK, I think Citizendium may be the place to do a big history wiki. Specifically, I'm thinking of starting a little big history, Big History of the Mind, there. The advantage of Citizendium over Wikipedia is that Citizendium articles are not about the field, like in wikipedia tends to be, but are the actual scholarly content of the field, in summarized form of course. Citizendium is extensively referenced with scholarly publications, whereas Wikipedia includes citations from the popular press. Also, all contributors and editors use their real names in Citizendium, whereas in Wikipedia they tend to use aliases. Any thoughts, anyone?
