I can tell that you're trying to be sarcastic, but I've heard enough good things about Slack that it was hard to catch.

If you're not being sarcastic... well, I think Shank summed it up pretty well.

Lookit, I love Slack. Used it extensively in a huge team.

But I do get tired of the constant thing around HN whenever a company releases some new feature, people immediately post a "Well, credit should really go to XYZ who did it first".

Sometimes the other company did launch a similar feature first, sometimes the features aren't that similar, and more often than not, everyone is copying from everyone. (and that's ok)
