A system with comments attached with no poster 'real' identity pretty much warrants the dilemma yelp is facing now. What about a (food critics, etc.) system where all the comments come from your facebook friends? Would that significantly reduce the inaccurate info the user will see? People can still register fake accounts to make unfair comments but the stores do not need to worry because it is likely their potential customer will not make friends with these 'fake people/account'. And the one makes comment will be much more accurate because all of their friends can see his/her comment, so his/her comments have many social implications so most people will not purposely write some unfair comment.

Yeah, you usually don't go asking strangers for a good dentist, you ask friends, or maybe their friends. That's the whole point of recommendations.
