The Who bot is AWESOME. I noticed that it doesn't access the skills or what can you ask me about from Delve. This would be an easy way to get some positive hits and jumpstart its use for orgs that are just getting started in teams. It would also be nice to point teams to this as a 100% hit with loose conversations in teams in a separate section or an option to "include channel conversations in bot results". This would help to replace a lot of "who can I ask sheets" in the office.
