Sorry to write such a long blog post, but I didn't have time to write a short one. Another solution is an appendix, as a sort of purgatory for zombie passages.

Sorry to write such a long blog post, but I didn't have time to write a short one. Another solution is an appendix, as a sort of purgatory for zombie passages. Or a short and long version of the same blog post - your own tl;dr. Perhaps best is the idea of chapters: treat the first blog post as an introduction or introductory chapter (or even as an abstract thereof), and the cool sentences you think of - that in reality are expansions of the main point - can move to a chapter, where they become first-class citizens, being directly relevant to that chapter's own thesis. Each chapter is a blog-post (and named, and linked to, as such). If you don't yet have enough material for one of these chapters, leave it as a draft for a while (or publish it as a skeletal chapter). Read over your com­po­si­tions, and where ever you meet with a pas­sage which you think is par­tic­u­larly fine, strike it out. aka kill your darlings
