Why Facebook comments is a bad idea for your site 14 years ago
+1 gdilla, I completely agree with you. It also gives context behind who the commenter so I can make judgement whether to trust the author or not. This is one of the primary reasons I like use Quora (over Yahoo Answers w/ fake avatars) and read the replies to questions because I feel like that it's a real person with a real identity who is talking. Sites that use FB create effective barriers that bridges the gap between the offline and online world.
