I mean those who earn a living from doing that. I'm not talking about users of products who report on the internet what their experiences are. I think those are definitely valuable assuming they are NOT being paid for saying bad things by competitors or saying good things by the subject they are commenting about. I have found that to be valuable. As for the others? I don't trust them. You don't know what their tastes are. Whether they have an ax to grind and are engaging in PAYBACK. If THEY are getting paid big bucks to trash someone or rhapsodize about something/someone. I prefer to experience it for myself for myself and never bother with them. What about you? What do YOU do? Why?
