What is Slack?
Slack is a "messaging app for teams"
Allows for easy search
Sounds like email.
Problems with email
Email requires a balance of keeping people in the loop, and flooding their inboxes.
Requires careful use of cc to keep everyone in the conversation.
Easy to lose emails - e.g. hermes file limit.
Easy to miss replies in long email chains.
Easy to overlook relevant emails from the past.
Slack solves these problems
Much easier to find conversations that are relevant to you
Everything is automatically saved.
The conversation chain is easy to follow.
Everything is indexed, and a quick search will pick up anything previously mentioned.
