I think it depends on the hobby/forum. The parent mentioned automotive forums, and I would agree that I would much rather remember certain posters. The best written posts aren't always right, for some reason there's a large subset of people who will write an informative-sounding post containing incorrect information. If I'm asking what valve lash specs are or which pin # on a connector is the + EGR solenoid, then I don't care how typo ridden the post is if the information is correct. On a Ducati forum I read, one of the most knowledgeable posters writes at roughly a 5th grade level (combination of being a mechanic and non-native speaker). Doesn't matter, I recognize the profile pic and know that it's worth parsing, the information is likely more accurate than the manual.

Hiwever,for a general discussion that is non-technical, then I would agree that a newb's opinion carrying nearly the same weight as a regular is a good thing.
