I mute at here in all channels. It should be banned.
Using @here in a channel is the equivalent of standing on your desk and shouting at everyone around you. So what happens is, like you, everyone starts muting it.
And then you just have people shouting into the void.
It all boils down to how people use the communications channel. I see @here multiple times a week but do not feel like it is a big distraction. At worst it can create a few minutes of distraction from my current workflow and if I'm truly in the middle of a thought process I ignore the message for a little bit or unless a 2nd notification hits.
Never @ someone unless you want their immediate attention?
