Skype vs Slack
Skype started first, in 2003, 10 years before Slack.
Why Skype lasted
- The username graph of the 2000s still has grandparents on it.
- Microsoft cannot quite kill the brand without a press cycle.
Why Slack lasted
- It turned IRC-for-work into a company default and made search across chat a reason to stay.
- Salesforce bought it and the login did not vanish, which is the adult form of surviving.
