The "Squeak Swiki" is a large and active Wiki that documents Squeak Smalltalk. You will see many references to its old home at minnow.cc.gatech.edu 
, but most page addresses can be translated to its later address at
wiki.squeak.org
where it moved in the mid 2000s.
Squeak Wiki can also mean a squeak based wiki which can be used for a Personal Wiki.
Of the Squeak-based Wikis, the Comanche swiki was for a long time the most popular codebase:
wiki.squeak.org
Smallwiki was another, which was ported to Seaside Framework and its name was changed to Pier Cms.
Free Squeak Wiki hosting is available at www.netunify.com (formerly Swiki Dot Net)
See seasidehosting.st for free hosting of Pier Cms wikis and websites.
I have used an old version of Squeak Wiki for years as a way of storing personal content. My main problem with this is how to convert the information into other formats which did not exist when I started. -- John Fletcher
