Yeah. I can see what you mean. They work on a big screen for me, though. But maybe some of them are little on the large side for smartphones. I find lots of very short paragraphs a total turn off, for reading on a PC, so it's a tricky balance. Thank you. :)
I notice news sites do sometimes have short paras, but they also have much less white space between paras than Medium, so you don't get the sense that you're looking at a list when you're on a PC, because there's still a good follow on from one point to the next. Not a massive paragraph return. I do try to bear mobile readers in mind and balance it.
