I think for the vast majority if you are on the up and up then you shouldn't worry about things like this. However, I would personally rather see complaints on sites like a pp mentioned where there is room for both positive and negative commentary. I found my ob that I adore on a site like that for doctors. I'll also give my honest opinion on teachers and the issues of professionalism and respect. There are bad and good- and no, I don't automatically give teachers credit until I know them. Of course I am courteous etc. but I see enough banter on my fb, where about 20 of my friends are teachers, to know that they are not all pillars of the educational community. A shocking number of them can't even get their, there, and they're straight which scares me. So I would take anything I read online with a grain of salt, but I also don't think teachers as a whole are somehow above any nonsense that I'm glad parents have an easier time of finding out about now with the internet.
