Bruce Elgort happily ditched the online discussion forums he used for three community college Web development classes he teaches and replaced them with Slack, a group chat application that’s becoming the darling of workforce communication and collaboration.
While older enterprise social networks and collaboration tools such as Chatter, Jive and Yammer reside on a company intranet, Slack works like any other iPhone, iPad or Android app. It’s also free, at least for the most basic edition. Versions with more message archiving, user support and analytics start at under $7 a month. Slack spokeswoman Katie Wattie said the San Francisco startup is working on a beefier enterprise-level version that will debut later this year.
