Not only is being FORCED to click ~27 times completely wasteful of your readers' time, it is also nonsensical to have a "Read more" and "Read less" option that hides 3 sentences. You literally have to click over 50 times (half of those in different locations since the text is always different) to read this article.
Seriously, 4 year olds are not reading your articles. If someone DOESN'T want to read more, why on Earth would they not just STOP READING. Do you have an option that says "Stop looking at pictures"? How about an option that says "Stop having ADD and being illiterate"?
Are you afraid that 15 sentences might entice readers but 18 sentences are going to scare them away? What planet are we from that this makes sense...as a scientist and computer programmer I always try to be as skeptical as possible that I am wrong and think of ANY possible mistake or oversight that I have made, but I cannot think of ANYTHING that would explain these ludicrous layout choices.
If I have clicked "Read more" 15 times, maybe just maybe you should keep track of that and not force me to click ANOTHER 15 times? Do most readers have such an attention deficit that they have to reconfirm to you their intent to read your article every 30 seconds?!
