This looks great. For public communities / support things I start in the future I'll seriously consider it. For my _current_ non-work slack things.... i really _don't_ want them to be google indexed. Having the ability to disable google indexing would be a big deal for me, and if available would make me seriously consider switching our current slack off of it. We really don't like the 90 day data limit, but it's a small private group and we're not about to pay whatever the monthly per-seat fee is just to be able to search our past stuff. Also, I love the !mention vs @mention distinction.
