I'm not even sure how to make it social, so that's certainly not high on my list of things that need to be done. A lot of the design is such as it is because I was scratching my own itch, and I have no love of in-your-face UIs (I didn't fully succeed here, but I can't justify a lot more work unless I get some actual traffic.)
To make it social, let people define other (non-wikipedia) documents that are tied to terms, at least for linking up their own work. This will make it more useful for SEO, and specific unique domains. Then let people share wordlists, and select wordlists to use on a per-post basis (or maybe your code already has the smarts for this.) The result should be that if I write a post about an arcane topic, the jargon is linked to my favorite references on the subject.
Something to consider: instead of embedding direct links, use redirection so you get a record of every time a link is clicked on.
If you have the need for such a designer, I'm open for contracts or would be more than willing to outsource the work to some of my associates in case I get tied up by then.
