In the recent months, I've seen that many friends (many of them coders) started writing, long, elaborate mails with footnotes for link, meaning that they write paragraphs [1] and then [2] put the links at the bottom [3]. Like this.
[1] www.example.com/1
[2] www.example.com/2
[3] www.example.com/3
I think it is smart and everything, but I don't understand the process of putting the numbers while you write: I put the reference both when I write and when I edit the text, I swap paragraphs, thus I make a mess with numbers.
Is it a common practice used by some community or is there some editor/plugin that automatically puts the right number in footnotes? Is this mutated from Markdown?
