Short forms never make money which is why I don't know why people swear by them. We get paid by read time. If you write a minute read you're making what? A cent? The god and goddess of short form basically only write that. They writer other stuff but SF is how they got their start here.
I do a few if it's too long for a tweet but now many. I did the death announcement last year when they found Gabby's body. SF. 61k external views which meant I didn't make a cent even though it went viral. The new CEO is thinking about changing that.
