Ironic coming from Bloomberg which is known among the financial services, as a joke, as the most expensive messaging system available.<p>I used to work for Bloomy for 3 years, and all the workflows for a Bloomberg employee are tied into the terminal, from email to chat.<p>That having said, I'm sure the person who wrote this article has never used Slack at work, and as a journalist he surely does not see the value added of being able to format code/send files/create polls as easily as slack allows you.<p>Comparing it to email is pure stupidity and displays a lack of understand of the product. But to be honest, I didn't expect more from Bloomberg Businessweek.
