My cranky-day rant about people /msg-ing in work IRC
People keep /MSG-ing me non-secret things in IRC, so I assume everyone's doing it w/ one another too. Everytime someone /msg-s me I ask them to bring it up in the main channel instead, but that's not getting the message across, so: STOP IT.
The whole point of IRC is that there's huge benefit in everyone overhearing things that they're not currently working on. This is why IRC is 1000x better for a tech group than IM. There's incredible value in making things like "Oh, I did that at my last job, consider looking at X" or "Didn't I see you did something with Y last month?" possible, and all of that gets flushed down the drain when you /msg.
Don't worry about the channel getting too chatty. I'm in some channels w/ 200+ members and it works just fine. Your IRC client will figure it out.
There might be no immediate need for [Alice] to hear [Bob] and I discussing the finer points of dynamo throughput settings, but there's no harm in it and if at the end of the month the bill knocks her socks off she's goin
