Hello everyone,
I don't believe Slack will kill email, but for conversations, especially in communities, and categorizing discussions, I think it gives email a run for its money. It has massive adoption in the local tech scene--a sizable number of companies use it internally. It's also doing well in the open source community. Ember's Slack killed its IRC channel.
Feel free to jump in and join the conversations or announce job opportunities or upcoming events.
Regards,
Yaw
