Doorway pages are typically large sets of poor-quality pages where each page is optimized for a specific keyword or phrase.
The sites would be high quality, lengthy, covering all aspects of their subject and not necessarily a keyword. Doesn't exactly fit the mold.
Whether deployed across many domains or established within one domain, doorway pages tend to frustrate users, and are in violation of our Webmaster Guidelines.
I doubt these would frustrate users, if they do then wikipedia would also qualify as frustrating.
Google's aim is to give our users the most valuable and relevant search results.
Page value would be extremely high, there just aren't any other pages.
ADDED: Sorry, I just noticed that this was in the Bing forum.
No problem, Google isn't the only engine in town :-)
My gut tells me that if they are truly authoritative pages, providing great value, they should be fine but my gut also tells me that "single page with link" might send a search spam rep to the spam button quickly just because it is only one page. It's funny that a parked page poses no risk but actually placing content on a single page has me worried.
