On Twitter, that’s looking for a needle in a haystack. While F4F on Medium violates its policy, there is no such policy on Twitter. No money to be earned would be my guess.
Twitter is like a short version of LinkedIn in my experience. It’s all about networking and making connections. Since I decided to take some time to invest in Twitter I’ve sold a few more books and have linked up with other Medium writers that I didn’t know exist, nor did I for them. So now I’m getting more reads which means more money here.
Although on most days I feel like the little paperboy on the street corner yelling and hawking papers for a nickel.
