Yahoo! posted a new blog entry last night named Going deeper into the Wikipedia which describes Yahoo!'s approach to utilizing the Wikipedia. If you do a search and a wiki result is found within the SERPs, no matter if it is #1 or 100, it shows "Quick Links" to deeper wiki pages. For example, conduct a search on coffee and scroll down to the wiki result. You will see links to "Etymology and history - The cafe - Coffee bean types" on the site of Quick Links.
Google's approach is a bit different, they place the Wikipedia results, when they deem it appropriate, in the One Box location. Giving them prime real estate, and placing wikipedia results at the top, which may not be as useful as the way Yahoo! does it. So does Google still treat Wiki too well?
