This is by far better approach yes (and as you say on your page, really its all just a bit of tweaking, not a technical redesign); Wikipedia's content is, IMHO, way too rich to thrive with the minimalist/huge-blog-font combo in OP's link.

Thanks. I think the structure and organisation of articles on Wikipedia is pretty sound, but some visual tweaks can help make the page more easily scannable and a litte bit more aesthetically pleasing (which I realise is a very subjective thing!)
