It's a real shame that TL;DR has now become the norm. I can't find the link right now but there was an article somewhere stating that the TL;DR is a redundant construct because if you want to summarize your article you should do it at the top, in the first paragraph. That first paragraph is called an "Introduction". Funny enough the author of the blog post wrote a good introduction to his article, but chose to tack a TL;DR to it.
