Yes, we are part of the boost program. As are many publications here. Medium is also revamping it — I just got an email about the changes. Pieces that are boost-worthy are put forward to Medium by the ‘assigned’ booster. So here’s my advice — if you enjoy being boosted (and we all do!) produce boost-worthy pieces. Go to the Medium website & read what THEY are looking for. Publications do not have the power to boost, but only to submit pieces to the Medium Boosting Team who then make the decision. I’ve had several pieces up to be boosted and the powers that be at Medium did not agree with the person(s) who submitted the pieces. In the last year, I’ve managed to get about three pieces boosted. The standards are high and Crow’s Feet & her editors are not the entity that makes the final decision about boosting. One doesn't get boosted simply by asking. Write good work & it will get noticed.
I hope this was helpful.
