I dont get twitter and the modern tech industry. Apparently, innovation is just copying other companies features. Facebook did this in an attempt to destroy WhatsApp. Instagram gets all of its features pillaged by companies.

I don't say that to imply Dorsey is a poor leader, or that he hasn't done a good job at Twitter, but I will say is that it's hard to argue that Twitter has lagged behind its peers. It just today announced it is testing a new feature called "Fleets," which is basically Instagram Stories. It also has struggled to figure out how to deal with fake news and misinformation that regularly spreads on its platform. Oh, and let's not forget the bots and trolls.

Apparently Jack Dorsey just didnt have time to commit to Twitter and will focus his efforts on his other company, Square. I doubt if there is any saving Twitter after they banned President Donald Trump.
