The last is the most important for me, and I'm not sure how I feel about being able to turn it off. I've been known to post an many paragraph entry, with only the final paragraph hidden. It is much like the joy of memepool style linking -- that the cut-tag is part of the story. The suspense of what my text says. The suprise in my last entry, for example -- if you didn't click, you missed it but who cares?
Or they are used as an outline of the entry, so that one can decide to read on or not. I don't worry about people failing to click-through -- I don't worry about my audience except in negatively impacting their livejournal experience.
I guess lj-cuts never really seemed much of a problem, and most of my friends effectively use them. But what I think the post was really about was the evangellical nature of some lj-cut users. Communities like ljcut and etiquette_lj, or the occasional person who bitches about a long entry. Whatever. I like the well-written and illustrated posts some friends do. I like the massively lj-cut partitioned entries. I'm less fond of the pages-long entries that are a single paragraph, but those are both often the drunkposts. And regardless, it is not my place to comment on how someone else formats their post. Unless it disrupts my friends page -- like, posting 25 copies of the same entry would be bad. apod already screws with my baseline, but I'm not about to turn off inlining, because I won't have enough motivation to look at the pretty pictures, and I'm only syndicated because I like the daily pretty pictures.
We are all silly. It is livejournal. It is like emotional crazygas.
