Slack
8.5Channel-based team messaging platform that became the default alternative to email for internal communication.
Strengths
- Channel model scales better than email for team-wide and cross-team communication
- Massive app/integration ecosystem connects nearly every other tool a team uses
- Huddles make quick synchronous conversations frictionless
- Search across message history is fast and reliable even in large workspaces
Trade-offs
- Notification overload is a common complaint without careful channel discipline
- Message history on the free plan is limited
- Can become a constant-interruption tool if norms aren't set deliberately
