I've no doubt that there are some 'power users' who tend to err on the side of arrogance, however there are plenty of well known users who's opinions I actively seek out simply because they are experts in their field and their insights are valuable.
You would still be able to see the comments from a particular user by visiting their profile and going through their comments (I know that that's not ideal), but assuming that an opinion is the right one just because of who said it is dangerous.
