The preponderance of online reviews speaks to their basic weakness "The preponderance of online reviews speaks to their basic weakness: Because it’s essentially free to post a review, it’s all too easy to dash off thoughtless praise or criticism, or, worse, to construct deliberately misleading reviews without facing any consequences." Anybody can tell me what the "The preponderance of online reviews speaks to their basic weakness" means in this context? Does this mean "The strong points and weak points of online reviews go hand in hand?" Pls help me. Thanks in advance. :)
