Keybase just launched their teams feature (think encrypted Slack) and you can read more here: https://techcrunch.com/2017/09/18/keybase-launches-fully-encrypted-slack-like-communications-tool-and-its-free/
The reason I am posting this is they have supported Zcash addresses (both taddr and zaddr) in Keybase profiles for some time. Here’s their rationale for choosing ZEC over other coins: https://keybase.io/blog/keybase-and-zcash
Anyway, given this well-polished product, it should mean more exposure for Zcash in general which is a good thing.
