This document summarizes a study analyzing how Elon Musk's acquisition of Twitter in late 2022 impacted the tweeting behaviors of self-described entrepreneurs. The study found that most entrepreneurs (over 50%) did not change their tweeting patterns in response to the acquisition and can be considered "Musk-donotcares." A small percentage (under 2%) increased references to Musk and engagement and are termed "Musk-lovers." An even smaller group (under 4%) decreased Twitter usage and are termed "Musk-haters." Overall, the study found the "Musk effect" to be largely a "Non-Musk effect" as most entrepreneurs were unaffected in their Twitter behaviors.
