Someone just did an analysis on the statistics of The Magic Cafe. Posting there has declined significantly as well:
I wish I could say it wasn't, but yes - it is.
At this point, I wonder if even Reddit is doing as well as other, more video-/image-oriented social media sites, like Instagram or Facebook. I get the feeling that the sites that are more visually engaging are more of interest to a modern audience. Too many words, and the eyes start to glaze over...
I used to have a friend who, despite being around the same age as me, was more like a millennial in his mindset. Any time I sent him an email with more that two sentences, his attention span tripped its circuit breaker! Many people, especially younger people, would rather be given visual information than something to read, having been brought up in a very visual age.
