Ugh, /g/ is pleb-filled unfortunately. The majority of the threads illicit facepalms because the crowd there, while not as bad as Redditors, politically, are quite shallow in their expertise. Simply put, a lot of nerds who don't really know a lot, especially when it comes to what hackernews specializes in. It's likely due to it being the only place on 4chan people feel their desktop/tech support thread fits on.
