I haven't used Discord but if it's better than Slack you are sitting on a huge opportunity. I know your focus is gamers but the market Slack is targeting is huge. Their mobile app is garbage (at least on android). Always 'reconnecting'. Doesn't keep the recent chats offline and has to always fetch it from server. Missing/delayed notifications. Desktop app on OS X is better but it too has 'connection issues'.

It looks like we will be able to use Discord when you add search. Seriously, tell the management to think about it being an alternative to Slack. We are a paying Slack customer and while they are better than hipchat/IRC, it is far from perfect.
