Tell HN: Everything Needs a TLDR
If you are reading something online which does not clearly tell you what it is about or a strong hint of its conclusion, then you are likely just a pair of eyes which are measured by advertising value.
A "tldr" - "too long, didn't read" gives us the summary at the start, before we waste our valuable time reading words which may be multiplied and expanded with the intent to keep us reading longer.
In times past there were bookstores. You could flip through a book, TLDRing your way toward the end. If you found enough sections of value you would buy it. On the web, we can't flip (unless it's a PDF, which may even be worse).
Always consider the source of the information. What is their motive, how do the earn money to survive? Do they really want to share information, or do they just want to lure advertising targets? Well written, summary-first content can tell you this quickly and potentially save you hours each week.
