I'm trying hard to understand why it has to be a personal channel. Water coolers aren't personal, that's the whole point.
In particular you're still adjusting what you write to be OK for anyone in your team read, so the distinction with the other "casual" channels sounds thin.
OTOH if your team doesn't have a casual place to say random stuff, it would be a nice improvement to get one.
I am conscious of double posting, and bumping other people's messages off of the page too soon. If I'm posting too much I get annoyed at myself on behalf of other people. So that would be a big plus of these channels to me.
It might not help in all situations, but I see some people threading their posts to avoid that effect and somewhat keep a context to their thoughts if someone wants to jump in.
Common channels can also work nice, but sometimes there is a vocal few who absolutely dominates them, and then the other people won't participate at all. The idea in TFA is to everyone have their own channel, where others cannot start a topic, so they don't stifle those who communicate less.
The reason it's analogous to water-cooler talk for each person to have their own channel is because when you go to get some water, and see other coworkers milling about, you're going to know which coworker you're interested in talking to, who often has interesting insights, who might have something interesting going on in their personal life that you'd like to hear more about. So, in the absence of a common meeting space, you can go check out the channels of people you're interested in, and scroll through to see if they've got anything interesting going on in their life.
