Slack Closes $250M Funding Round at $5B Valuation
Despite all the detractors, Slack definitely made collaboration much easier b/w teams. IRC was just too techy for tech and non-tech teams to collaborate.However, I don't think the future of collaboration will be Slack. It is just too expensive and quite buggy at the moment. I'm hoping there will be competition that will either make Slack better or replace Slack with a cheaper, less buggy alternative.
