I can finally have a single platform for communication. Voice chat, text chat, group chats, friends list, async communication, unlimited logs (no 10k max msg nonsense), webhooks/integrations that let me do far more than IRC bots ever did. All of it under one account. Oh and the client doesn't suck, unlike Slack's. It's fast. The voice quality is superb.

As far as productivity goes, I get far more done with it than I ever did with IRC. The addition of being able to hop on voice very quickly is insanely good. Screensharing and video chat coming this year as well, I'm pretty excited.

It's to the point that I bought Discord Nitro (their premium offering) the day it was released, for no other reason than to give them money.

I hope the question of protocol openness gets resolved; until then, IRC just doesn't cut it for me anymore. IRCCloud.com helps, but their interface is super slow with lots of channels and IRC itself simply has no support for the thousands of improvements that have been made in communications the past 30-something years.

Short of video calls though, Discord is essentially a drop-in replacement to Slack. We've been using it at my company, it works so damn well. I moved to it for our open source community as well. I use Matterbridge for a three-way mirror between IRC and Gitter as well: https://github.com/42wim/matterbridge/

You can use Discord any want you want. If you join some popular Discord server, odds are it'll be full of spam and Internet humor, but obviously you can do whatever like on your own server(s).

> I'd be forced to use their awful client

Who forces you ? You can use slack on the web can't you ? You don't need to have yet another browser engine running on you computer.

> Just use IRC.

Please don't … IRC is the opposite of user friendly: it has no good web interface so the casual user won't come in because he doesn't want to install and learn a new software (IRC client). But slack isn't the only option here, it's not even the best open by far, Gitter[1], Mattermost[2] and Discord[3] are alternatives to IRC which aren't Slack.

[1]: https://gitter.im/ [2]: https://about.mattermost.com/, they don't provide chat hosting but several organisation do host mattermost servers (Framasoft for instance https://framateam.org/) [3]: https://discordapp.com/ targeted at gamers, which is a good sign of quality, but fine for general purpose use.

Slack's web client is still slow. Their "native" client is just a Chrome wrapper over their web app, with some glue code to hook up notifications.

> it has no good web interface so the casual user won't come in

https://webchat.freenode.net works fine. If you need or want help with a project and can't be asked to spend a few moments opening up an IRC client (native or web), then I don't know what to tell you.

> Gitter, Mattermost, and Discord

Gitter and Discord are both closed source, proprietary systems made by companies who want to make money. Open source projects shouldn't rely on them if possible.

Mattermost is OK, but requires running your own server. IRC is free, and there are public servers specifically made for open source projects.

Curious if this statement is about the most recent experience post improvements mentioned in tfa?
