I have to think that the new post formats on Facebook which let you make your status update A HUGE FONT ON A COLORED BACKGROUND represent the ultimate antipattern and the death of good design at the hands of metrics-driven optimization.
They surely exist because so many A/B tests over the years made pieces of Facebook’s UI bigger, louder, and more image-heavy because all those changes encouraged more clicking and addiction and “engagement.”
Then one day someone at Facebook observed that everyone had stopped doing what they’d signed up for in the first place: reading the status updates their friends posted.
So of course this modern day Picasso decided to make status updates BIG AND SHINY AND BRIGHT RED too!
It’s Comic Sans and the marquee tag v2.0. Actually, this is more like v5.0.
