Not sure what you mean about Slack encouraging disjointed chats. It supports threading too and people use it almost all the time at my work.
I agree it is hard to find things again, but that's mostly because Slack's search is pretty bad, not because of any inherent properties. It's no easier to find old emails or old IRC messages or even wiki pages.
