I actually liked Hipchat. It did what it was supposed to do - provide instant chat with colleagues - without the overhead and frills of Slack. It was simple and reliable. I'm not sure why it was so disliked.
Then they decided that they wanted to look serious, and reduced the meme size to 32px. That’s when the product fell out of fashion, because it was just like Slack with fewer features.
Thousands of years of linguistic progress out the window...
