Your appeal 

But Wikipedia is more than a website. We share a common cause: Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge. That's our commitment.

If you really want to attract serious, knowledgeable people and see the Wikipedia financially supported - then you must to do (or, at least, initiate) a huge cleanup of the existing list of contributors and administrators. Many of the Wikipedia articles and talk pages are no more than a sewer of primitivism, lies, and political propaganda.
