I have to say it's really frustrating to duplicate functionality (in any way). This is what has happened to Slack, Quip, Salesforce and for that matter Facebook, Instagram and Twitter. I want one way to view code (Vim), one way to view a .jpg (feh), one way to ask quick questions (IRC), one way to quickly browse text (Lynx), one way to communicate structured messages (email)... but alas it falls apart due to the fact that we work as social creatures.
