I spent a part of my Sunday afternoon writing only to have lost the article due to an error on the server side. I may rewrite the article on another day, but I'm too disappointed to do a repeat today.
It's my own fault as I know better. Anytime you're writing an article, save your draft many times along the writing journey. Despite having the Internet rarely eating my homework these days, I'm disappointed in myself for not following this rule of mine.
