I've been increasingly using Slack in a number of different groups, which is awesome, because I love Slack. (For the uninitiated - Slack is a team communication platform.) I just learned about Slack snippets. You can have a whole conversation-within-a-conversation about a little bit - or "snippet" - of code or text. Handy little conversational segmentation feature.
Snippet real good.
