Larry Sanger was a co-founder and first paid editor of the free online encyclopedia Wikipedia.

Wikipedia has grown to be quite big. How do you plan on competing with them? Do you really think we need another wiki?
Sanger: I think we absolutely need another wiki--first of all, simply because Wikipedia lacks credibility, unfortunately. It's a good starting place, as people say--on some subjects anyway--but it isn't really what we want out of a reliable reference resource. And frankly, I don't think that the Wikipedia community is prepared to make the changes that I think need to be made in order to transform Wikipedia into something that's really reliable.

Integrity problem. The new site tries to compete with a "good enough solution". History shows that this approach rarely leads to success. Maybe there's a specialization area where they can establish credibility.
