May be his tweets were a reflection of his inner journey and struggle with where the company was headed? Let's be kind. This is not easy.
I have been following Atrium almost since its inception after being flagged by Andreessen and Justin was from the beginning tweeting pseudo-inspirational thoughts. In interviews he seemed more concerned with the story (serial entrepreneur / Twitch founder aims to disrupt legal field) than the content of the company (why the hybrid model? how is this going to move forward?).
I'm sure the amount of attention he dedicated to his tweets was vanishingly small compared to his startup. Why did his tweets trigger you?
