   Integral ▲760

   i've been a power user of slack/discord and etc. since i was a kid and i dont like the fact that they get unusable/noisy after 20 members join. so i designed integral to get rid of the 2 biggest causes of noise on slack/discord and similar apps: 1. channels 2. recency based feed i've replaced these 2 with a few subtle features (different approaches for business vs communities). check it out and let me know what you think :)
