Wiki

• Wiki supposedly uses an easier “Mark up” than HTML (Hyper Text Mark Up).
• A web site using Wiki usually allows some access to non-administrators.

Wikipedia

• Wikipedia is a collection of encyclopedias (in multiple languages)
  Contributed and managed by volunteers.
• There are guidelines for Wiki publications such as Wikipedia and WikiMedia.
• For example, an article for a Wikipedia should have citations, but it should not be a report for one’s research.
• A reader can challenge an article for correctness, style, structure, and conformance.
• I suggested and corrected discrepancies in some Wikipedia articles.
