Writing a post with footnotes has never been easier and cleaner before. All you need to do is anchor a footnote at any point and then write it on the end of the paragraph or wherever it fits you.
Usage
To anchor a footnote use the {{FOOTNOTE_NUMBER}}. Then to write the body of it you need to embrace it with [[FOOTNOTE_NUMBER]]. Here is an example:
—— document starts here ——- 
Lorem ipsum dolor sit amet, con sectetuer adipiscing elit, sed diam 
tempor incidunt ut labore et dolore magna ali quarn erat volupat.{{1}} 
venian, quis nostrud exerci tation ullamcorper{{2}} suscipit laboris 
commodo consequat. Duis autem vel eum irure dolore
[[1]]This is the first footnote.[[1]] 
[[2]]This is the second footnote.[[2]]
This is the next paragraph. Lorem ipsum dolor sit amet, con sectetuer 
adipiscing elit, sed diam nonnumy nibh euismod tempor incidunt ut 
labore et dolore magna ali quarn erat volupat. Ut wisi enim ad minim. 
—— document ends here ———
When the document is parsed, the footnotes that are between paragraphs will be removed from where they are and placed at the end of the document. The {{1}} will be replaced with an anchor link to the footnote. The footnotes will be a list having and anchor link back to the place the text has it. Here is what roughly the above text will look like after parsing:
—— document starts here ——- 
Lorem ipsum dolor sit amet, con sectetuer adipiscing elit, sed diam 
tempor incidunt ut labore et dolore magna ali quarn erat volupat.[1] 
venian, quis nostrud exerci tation ullamcorper[2] suscipit laboris 
commodo consequat. Duis autem vel eum irure dolore
This is the next paragraph. Lorem ipsum dolor sit amet, con sectetuer 
adipiscing elit, sed diam nonnumy nibh euismod tempor incidunt ut 
labore et dolore magna ali quarn erat volupat. Ut wisi enim ad minim.
FOOTNOTES 
1. This is the first footnote. 
2. This is the second footnote. 
—— document ends here ———
The up arrows and the [1] and [2] are the links. There are a few options that you can tweak, for now it’s in the code. Please refer to the plugin’s homepage at: http://www.stratos.me/wp-plugins/yafootnotes

YAFootnotes

Yet Another Footnotes (YAFootnotes) is a plugin that gives you the ability to add footnotes to any text you are writing.

Adam J. Seidl

This plugin allows an author to include footnotes in text by enclosing the note in doubled parenthesis ((Note.)) When the content is shown to the end user, the notes are removed from the text and included in the style of a footnote. Hovering over the footnote link will displays a popup with the footnotes content. Notes are also gathered and listed at the bottom of the page.

AJS Footnotes

Produces attractive, footnotes that are capable of containing HTML data, like images or links, simply by including them in the text.
