Do all your contacts work in the tech industry? I'm wondering if we're really backwards here in Australia, or if I've just had bad experiences. Slack-style messaging seems really uncommon outside tech, even though traditional AIM-style IM is used everywhere. I think a lot of enterprises could benefit from capturing corporate knowledge in searchable Slack channels, but the only teams I see using them are doing IT and software.
