The problem about this is that a LOT of users that seem knowledgeable pull shit out of their ass. I've seen this many times here: I read the article and then the comments and they just end up being elaborate bullshit based on a title and previous "knowledge" (often refuted by the article itself) rather than informed discussion.
This goes both ways. Articles aren't always 100% trustworthy either, and in that case a commenter might just as well offer a valid counterpoint or correction(s).
As with anything, be reasonable. If you're really interested, then use whatever content is available to educate yourself, be it comments, the article itself, or independent research.
I agree, the cases that bother me are the ones where it's painfully obvious the commenter didn't read the article. I enjoy reading counterpoints and is one of the main reasons I read the comments.
