They could be (and even seem) much more self-evident (and valuable as a tl;dr) if they were one-sentence summaries instead of a copy-paste of a paragraph from the beginning of the linked page.
Its a tl;dr. If you write 12 sentences its hardly a tl;dr summary anymore.
I thought it was a pretty self-evident summary. The article is great too and goes in more detail, but i have trouble imagining anyone saw that summary post, and was like "pattern 11: no examples" - i have no idea what that could possibly mean
