Micchan,
Slack has it's purpose. Do you feel the same way about discord? Trying to coordinate war hits on the forums compared to either slack or discord is asinine. Slack made us better in the last war for a number of reasons, the amount of extra things we have incorporated on to slack to give us fast notice on a number of different fronts (I won't list them all here - I am not certain this is a fully opsec channel) also makes us better. The whole "lets kill slack thing" is cute, but frankly you need to try it out and I am certain you will find real value there. Yes, long live the forum fighters and rah rah rah for the forums, but you need to try it before you continue to knock it. It has it's purpose and it is very valuable in that purpose. I am betting a lot of people would agree with this take... basically anyone who has been on slack as it stands today. Try it out... even if it is under a pseudonym, so you can understand. The worst thing that happens is you learn more about the "slack enemy you wish to kill".
