Like a lot of things, whether this is good or bad depends entirely on how it's used and who the intended beneficiary is.

Explaining a problem out loud often helps solve it, I know some of my coworkers can easily resolve an issue that might take me hours to fix myself, and deciding whether to ask for help (and who to ask, and how to ask them...) is frustrating as well. In theory, this could remove a lot of headaches from my day-to-day work. If I'm the one being interrupted and asked for help, so long as that's not constant (either interruptions are infrequent, or I'm only "on call" once a week or something), I don't mind helping coworkers troubleshoot.

I could see something like this being fine in a worker-owned environment. The problems (it can be turned into an inquisition, if you're fired in that inquisition you lose the ability to put a roof over your head and food on the table, it's likely to stay in place even if everyone hates it, someone else is pocketing all the benefits even if it works great) have more to do with capitalism than with this as a management idea.
