Slack is actually an acronym

The name of one of the world's fastest growing messaging apps appeared pretty self-explanatory. "Slack" seemed like a simple nod to what you shouldn't be doing at work.

Turns out it was actually an acronym. It stands for Searchable Log of All Communication and Knowledge.

In response to a Twitter inquiry last night, the co-founder and CEO of Slack, Steward Butterfield, explained that Slack came about as a better alternative to linefeed, the original codename for the now multibillion-dollar company.

This Tweet is currently unavailable. It might be loading or has been removed.

To prove the story was true, Butterfield uploaded a screenshot of a conversation with someone named Eric, likely Eric Costello, another co-founder of Slack.

Costello pointed out that the name could have negative connotations, but Butterfield thought the name could be funny. "Our users would be Slackers :)" he wrote.
