It took me a while to recognize the human face and the dog in the image, I think because I had just woken up. I read that post too and short posts are much more common on web2. I usually publish posts of average length and I agree with you, in art and some other subjects it's not the writing that matters. After all, if you are painting a landscape, you can take a few shots of it and write a short post underneath and share it. No need to be ridiculous to lengthen the post :P
Yeah it's not an actual human face or an actual dog. Yet it kind of is. Some might not see it all no matter how hard they look. Not all brains are the same, which is why not all content is the same, I guess.
It will be a bit ironic that I'm going to write a long post today as I plan to tell about my 1.5-year Hive adventure XD
There's no sense denying people do enjoy creating long posts. I'll experiment with shorts for awhile.
