Slack Factor
The ratio of the number of employees in a firm, to the number of Slack channels used by the firm. The higher the Slack Factor, the higher the number of Slack channels per employee, and the lower the possibility of finding that one message you know you just read a minute ago that you needed to respond to.
I just saw a question from Larry, but our Slack Factor is so high, I don't even remember what channel it was in any more. I guess he's not getting an answer.
