We have decided to make our Slack channel more attractive. On our team, most of the IM work-related correspondence is done on other channels (WhatsApp, Jabber), while our goal was to migrate these interactions to Slack. How were we to foster this change?

Slack allows the creation of external applications, which is a huge benefit. We harnessed the feature of custom commands to make Slack more amusing, and a bit of humor always gives motivation.
