Well, so much for a relaxed post-holiday week on Monday.News broke this morning that Twitter CEO Jack Dorsey is stepping down from the company entirely. The company's CTO, Parag Agrawal, will be taking over at the helm. Saleforce exec Bret Taylor will take over as board chairman.So, Amanda and Natasha and Alex jumped into onto the mics -- and, ironically, a Twitter space -- to riff on all things Jack and future of Twitter. From the show:Crypto and the CTO, what can we read from the tea leaves?Jack's dual role, and its detractors.The fact that Twitter's product work has been great lately, which we don't want to stop. When is a good time to leave a company, is it on the up and up or when things are quiet?And, finally, Jack's somewhat biting words regarding founder-led companies, which are, frankly, a bit at odds with his own behavior until now.The show is back on Wednesday, unless some other major CEO resigns.
