See, I see it differently. I think I am fully capable of making my own mind up, but it is nice to have some insight. As for what the kids post, well, I think we are all smart enough to know how kids are.
I looked up my older boys middle school and the two teachers I would have posted nice things about were listed and had a bunch of nice comments about them, but ONLY from students, no parents, so I posted nice things.
I also posted about my attorney, I actually added her to the list. Again, a good recommendation, not a bad word.
I can't say lately I've had any seriously negative experiences with businesses, but if I did, I would state facts on my post and let others take from it as they wish.
I love sites that give you consumer opinions. I would much rather go to a hairdresser, attorney, doctor and more, that was recommended highly by someone.
