Slack has only been in use for about five years, but it has exploded in that time. Earlier this year, it hit 8 million daily users, with 3 million of those paying for higher service levels. And it’s not like people are getting on Slack for a minute or two out of their busy day or sending a few isolated messages. A year ago (when Slack only had 6 million daily users), estimates indicated that paying customers were actively engaged in Slack conversations for better than two hours per day. Those users had the application open for a stunning 10 hours a day.
Needless to say, Slack is pumping out data at an inconceivable rate. Trying to collect potentially relevant electronically stored information (ESI) from Slack is like trying to drink from a firehose. There’s too much data coming in and too much of it is entirely irrelevant. Plus, it can be harder than you’d expect to siphon off the trivial side conversations so that you can focus on the important ones.
