just because you create slack channel for something.. or everything :D, doesn't mean that the reviewer will have more spare time to look at your PR. ;)
Right, I think Axolo makes it possible for your reviewer to respond quickly to something he sees and also makes it easy to be the next priority for your reviewer.
Do you think having dozens of channels pinging at you all day is a solution? I’d just snooze the channel if it barks too much at me.
