HipChat is probably under fire from Slack. That's why I think they are making this change, because I just made the transition a few weeks ago and Slack has been amazing. Once you go Slack, you never go back.
Any thoughts/justifications for pricing? The only thing holding us back is that Slack costs 4x as much ($8 instead of $2). While this isn't a big spend at the end of the day, we're sort of anchored at $2. There's nothing terribly wrong with hipchat, seems to address all our (simple) chat needs, and switching to slack doesn't seem to give us 4x as much value. So far the best reasoning I have is that we're a mostly-dev…
Even at the very cheapest end of the spectrum, a developer is going to cost at least $60 an hour, fully loaded. If slack can make them 6 minutes more productive a month (ie: 12 seconds a day), then slack is worth it. These are productivity differences that aren't even measurable in practice which means the rational thing to do is to just be price insensitive and adopt the tool that works best, regardless of cost.
