This post is poorly argued in my opinion. The author fails to provide an example of the "tools to summarize and communicate your thoughts" which he speaks of. As a result, the specifics of his argument are left to conjecture of the readers, producing an unfocused discussion. My take on 'TLDR'. It isn't typically equivalent to a well structured opening paragraph. As others have mentioned, it's more akin to an abstract, as used in academic writing. It denotes that the author will most likely use brief text to summarise and, for the sake of efficiency, it may be in a completely different writing style to the rest of the text. TLDR is a useful tool for allowing readers to make a rapid decision as to whether the following content is relevant to them. In some ways I see it as a courtesy to the reader.
