Not even in W3C's rather underrepresented suggested usage (as distinguished from common practice):
The objective of this technique is to use the HTML5 aside element to indicate that it's content is tangentially related to the main article or a parent section.

Dive Into HTML5 anaogises <aside> to sidebars:
The aside element represents a section of a page that consists of content that is tangentially related to the content around the aside element, and which could be considered separate from that content. Such sections are often represented as sidebars in printed typography. The element can be used for typographical effects like pull quotes or sidebars, for advertising, for groups of nav elements, and for other content that is considered separate from the main content of the page.
However, ctrl+f footnote doesn't return anything. What's the current best practice for writing footnotes with semantic html? If I were to implement footnotes with <aside>, how would it look like?

To the extent that Markdown does implement a specific footnote syntax, it's actually ahead of HTML in that regard.
