I love Slack. I love waking up in the morning to be told I need to upgrade to use exactly the same product as I'm forced to use every day, and which behaves exactly the same (except a bit slower) after I've updated my OS to install the latest browser to access Slack.

I love the bad search, the poor integration, and the web interface to a product with the functionality of an '80s app. It just burns so much time, but hey the wasted hours are all chargeable and that sure pays the bills.
