Sharepoint is a pile of shite. People use it as a replacement for a network share where they're used to dropping hundreds of excel, word and powerpoint docs. Now they simply embed the damned things in Sharepoint pages, which themselves are hidden away somewhere on the Sharepoint server. Its not easy to find resources in Sharepoint because the data you're looking for is almost always obscured by being hidden inside a document so the search never finds what you're really looking for.
A better solution would be to encourage people to use a real Wiki, and write a proper document to wiki page converter. Thats the only true stopper for take-up. Microsoft reckon they have a word to wiki converter, but it only exists for a specific verison of office vs sharepoint server. A basic word document converter does exist for MediaWiki, but that doesn't deal embedded images in the document.
