Slack is "where work happens," offering channel topics, direct messaging, and the overall ease of connecting with your audience unlike broadcast emails (Constant Contact, MailChimp, etc.). However, Slack is hard to navigate. It takes time to learn all of its features. Some folks, who are stridently against Facebook, were more willing to give Slack a try. But some Facebook users, who were stridently against sharing information with yet another social media platform, ignored my invitations. And others couldn't even get on to Slack with their company email accounts.
As I work with the folks who did sign up, I immediately realized a reduction in my need for sending out emails. Yet, I still had to make a round of phone calls to discuss the Pine Barrens Trail Center opening (not a bad way to spend my time), until I realized I had to call back everyone all over again to re-explain what was discussed. My team effort in building consensus would have been so much easier on Slack.
