Perhaps they (Seaterror, that is) meant "wiki farms that use MediaWiki", of which there would be a higher likelihood of visual overlap because out-of-the-box Mediawiki comes with Vector and Monobook (among other skins). Many on the (incredibly-non-exhaustive, I believe, but OTOH might be exhaustive as far as notable services by enwikpedia standards) list you linked don't use MediaWiki at all so of course they're not going to look like it unless they have some sort of equivalent skin on that farm's software. (This isn't an angry declaration or something. I'm just trying to lay out why a wiki farm that isn't Wikia wouldn't use Monobook or Vector.)

This, for example, is a different listing on mediawiki.org that is only allowed to list MediaWiki wiki hosts. (Note: It's still quite possible for a Mediawiki wiki to not look like Wikipedia anywho because of what that farm offers. Case in point: *points at computer screen*)
