I would assume the tech quality is similar to youtube comments.
I would say that is a fair assessment based on my own experiences in more than a few groups.
You usually have half a dozen people out of say 50 that know what they are talking about. Out of those 6 maybe 3 can actually articulate and convey the information. Then you have the incompetent cry babies who bitch to the owners/admins that you hurt their feeling because you told them they were wrong. It's a total joke.
