In a business context yeah it’s an attention stealing notification thing

But I mean more development communities that organize around pieces of tech. The idea is people voluntarily just hang out in the chat and respond to people in real time. There’s no obligation. You probably won’t get an answer if you don’t get one in the first couple hours. But in an active community you’ll likely get acknowledged quickly enough, at least with someone saying that your problem is non-trivial and that you’ll need to look at X to figure it out.

Such communities are often not designed for solving difficult problems so much as helping people get through the basics.
