I'm a member of Rands too, and I do think it adds some value, but I started this group as an email group because I generally don't think Slack works well for communities. It's one thing for Slack to be used at the workplace where people are usually "always on", but for a community, it's hard to have high value, long form discussions.
The email list discussions have blown me away. People will literally write 10 paragraph emails about their decades of experience, and because it's not in a chat format, all members can check their email whenever and see the thread.
