I think there is a lot of great contents in the wiki and, regarding the current objective of finding someone able and willing to migrate the Haskell codebase to another stack, I think it might be more efficient to create a homepage that explains the snowdrift concept a little further.
I copied the homepage and did some redesign suggestions here:
The goal is to get most of the concept and have a sense of how useful snowdrift could be without having to navigate through all the “learn more” and wiki pages.
I also change the subheadings from something purely descriptive of the contents that follows to something more benefit-oriented.
Hope that helps.
