- Nobody is sitting there waiting for their news feed to update.
- Nobody is posting information there as they would with friends because THEY ARE AT WORK, they worry their boss will see something stupid. This is why memes and other things rarely get posted on work networks.
- Nobody wants to seem like they are slacking off talking on social networks instead of working (even on the work one).
- No memes and other fun related things, nobody cares and nobody checks.
Slack on the other hand was a huge hit. We have a few groups of like minded people who just chat it up. Usually for short bursts. Everyone prefers it over the social network tools. And everyone stays active in it.
A major feature is the notification that someone sent you a direct message (might be important) or sent a message to a room (meh) or sent a message to a muted room (probably not important).
