Why do people keep coming back for more on Twitter? Blogs? Podcasts?
It is like a drug, getting great content is like the mouse in the cocaine experiment, he can press a lever for a pellet of cocaine or sugar. Inevitably he keeps pressing cocaine, as he likes the feeling.
I have absolutely no scientific proof but I suspect that is why once your in, your in.
You keep coming back to twitter for the great content & people you meet, the same with your favourite blogs they write in a fashion you understand, is relevant and what you demand. Podcasts the same.
You keep chasing that experience….
