Lookit, I love Slack.  Used it extensively in a huge team.<p>But I do get tired of the constant thing around HN whenever a company releases some new feature, people immediately post a &quot;Well, credit should really go to XYZ who did it first&quot;.<p>Sometimes the other company did launch a similar feature first, sometimes the features aren&#x27;t that similar, and more often than not, everyone is copying from everyone.  (and that&#x27;s ok)
