Wikis were designed to implement PatternLanguages

A pattern language is a structured method of describing good design practices within a particular domain. It is characterized by

1. Noticing and naming the common problems in a field of interest,
2. Describing the most effective solutions for meeting some stated goal,
3. Helping the designer move from problem to problem in a logical way, and
4. Allowing for many different paths through the design process.

Pattern languages are used to formalize decision-making values whose effectiveness becomes obvious with experience but that are difficult to document and pass on to novices.

http://en.wikipedia.org/wiki/Pattern_language#How_to_document_a_single_pattern shows that a consistent set of fields are required to document a pattern. Thus a StructuredWiki provides more support for pattern languages than one that does not provide this.
