Over 8 million people use Slack every single day to communicate in online teams, for work and sometimes play -- including us here at CNET -- and that number's about to get bigger now that Slack is merging with its rival, Atlassian's Hipchat. 

According to tweets from Slack CEO Stewart Butterfield, the new partnership with Atlassian (which also makes popular bug tracking software Jira, as well as Confluence, Bitbucket, and Trello for project management) means both Hipchat and its more recent team collaboration software Stride won't continue to exist -- they're getting killed off in favor of Slack.
