The Thinking Behind The Tweet

If you introduce your Interests people have a chance to understand what you want. Maybe they share your Interests. Maybe their Interests align with yours. Maybe they do not. If you introduce your Interests you, at least, have a fighting chance to know. 

If you express your Expectations people have a chance to understand what you want from them. Maybe they share your Expectations. Maybe their Expectations align with yours. Maybe they do not. If you express your Expectations you, at least, have a fighting chance to know.

And at least of equal importance, other people have a chance to know. If you want to accomplish things with the help of other people, you must agree you owe them that. 

Interests and Expectations: around the essence of communication. Just add story and repetition.
