How many types and categories of wikis are there in total and I want you all to find each and every one of them as a competition of what they are?

Wikis can be categorized into several types, including general-purpose wikis (like Wikipedia), specialized wikis (focusing on specific topics), corporate wikis (for internal company knowledge sharing), and personal wikis (for individual use). Additionally, there are collaborative wikis, educational wikis (used in academic settings), and community wikis (fostering community engagement). Each of these categories serves different purposes and audiences, highlighting the versatility and adaptability of wiki technology. The total number of types can vary based on classification criteria, but these are the most commonly recognized categories.
