Just for clarity, wiki-links and markdown are similar but different constructs. Wiki-links (the
[[bracketed]] entry) are a simplified method to insert a hyperlink in a document, including (in some wiki software) the ability to create the linked-to document or note when the newly-inserted wiki-link is clicked. Markdown also includes a simplified method to insert a hyperlink (the
[name](resource) entry). The confusion is not that markdown has superseded wiki-linking, it is that Tinderbox employs part of a wiki tag (the
[[) for the “quick-link” fearture, as @mwra points out.
It is not the case that wiki-links have to employ camelCase. Wiki Media does not, for example, in this source:
'''CamelCase''' ('''camel case''', '''camel caps''' or '''medial capitals''') is the practice of writing [[Compound (linguistics)|compound words]] or phrases so that each next word or abbreviation begins with a [[capitalization|capital letter]]. CamelCase usually starts with a capital. When used in a [[programming language]], it usually starts with a lowercase letter. Common examples are [[PowerPoint]] or [[iPhone]].
