group conversation — Slack has taken over group communication and messaging for work with its design of channels and the network. But there is still no great way to stay in touch with a group of friends. I have groups on iMessage, Telegram, GroupMe, and WhatsApp but they are pretty spread out and inconsistent. Every time I go to an event, a new group forms. I wish there was a core app where I captured some of my groups of friends and we stuck there and stayed in touch better.
