Been using HipChat for almost 3 years (so I believe, pre Atlassian, and post.) It seems well suited to purpose, and works fine for me. The only gripes I have are minor (for instance, their iOS offering has this infuriating behavior that it will notify you for direct messages, and throw up the old red dot on the app icon, but then provide no ability to see where the message came from when you open the app.) In light of how well it works, I am mystified as to how slack has managed to come in to the exact same space and carve out such a massive valuation. If there was ever an industry ripe for disruption, the "modern chat client with goofy icons that allows you to post gifs and search your chats without arcane IRC syntax" did not seem like one to me.
