C2Wiki

https://wiki.c2.com, created by Ward Cunningham, is the oldest Wiki. Yes, older than Wikipedia. This knowledge garden owes a debt to C2, partly because I drew a lot of inspiration from C2 Wiki early in my career as a software developer; there are many, many interesting pages on that Wiki. But, also because a few patterns in this knowledge garden are taken from there (for example, WikiNames.. and also how the whole thing is generally organized).
