What is Slack & Why Is it So Great?


Slack is a communication tool designed for remote workplaces. It is a single place for messaging, files, and tools with your colleagues.

The primary purpose of this platform is to establish communication between colleagues. There are two methods that you can use to chat on this platform.

One is the group chat or Slack channels, and the other one is the direct message for a person-to-person chat. 

When Slack came to being in 2009, there was no competition in the market. The competitors were there like BaseCamp, which was Campfire back then.

However, none of the traditional bug vendors, including Apple, Microsoft, Sun, IBM, and others, had anything against Slack.

Slack was able to tap into this situation and used it to its benefit. It was small in size, so it was highly responsive to add new features.

This platform did not have a big price tag either because it was not from any traditional big vendors. Slack gained its popularity mainly due to its design simplicity and understanding of what its users wanted.

These are the two aspects that are simple to understand but difficult to execute. And it has allowed the company to grow at a significant pace, especially in recent years.
