If I have seen further it is by standing on ye shoulders of Giants.

As any open-source project, this one has benefited from the contributions, both direct and indirect, of many people.
Among the various alternatives, I chose Instiki as the base for this project, because of the elegant code. If you’re going to build a quality application, it pays to start with a quality codebase. For that, I guess I should thank David Heinemeier Hansson, who wrote both the original version of Instiki and the Ruby on Rails framework on which it runs.
Andrea Censi, the author of Maruku, has been incredibly receptive to my suggestions and requests. To a large extent, the richness of this branch of Instiki is a reflection of the richness of Maruku and of his willingness to extend Maruku in the directions that would be most helpful here.
Jason Blevins has contributed many bugfixes and code improvements. Instiki is a much better application, thanks to his efforts.
Ari Stern contributed the BlahTeX/PNG support, for the luddites among you.
Andrew Stacey, Toby Bartels, and the crew at ncatlab.org have been extraordinarily helpful, finding bugs, suggesting new features, and giving the software a good stress-test, on what is surely the largest Instiki installation anywhere.
Sam Ruby inspired the original XHTML Sanitizer that I wrote for Instiki, ported it to HTML5lib, and coaxed me into joining that software project. Sam really knows his way around Rails, and has been a very helpful source of advice and encouragement. Thanks, Sam!
