SE's shouldn't be attributing ANY value to wikipedia links. They're nofollowed. If the SE's do attribute some value to those links, then the whole thing comes tumbling down. Frankly it wouldn't surprise me that Google was somehow using Wikipedia links in some way, but if they were it'd have to be a dark secret.
My thoughts were that a link on Wiki, on a top ranking page might yield secondary links.
Plus, I'm not filling gaps in their site with content - the content will be published on my website and merely linked to as a citation in Wikipedia.
Plus, creating the citation is directly helping sales. I've integrated into my sales conversation some of this new information and clients are impressed. And since clients in my industry are looking to deal with an expert (my product is generic, clients deal with me because of my expertise) initial results seem to indicate that they're more likely to buy. Particularly if I site a study I did, with results that are directly opposite the advice they receive elsewhere.
