@HappySqurriel: They can't complain to the FTC if the apple developer or scientist openly state their occupations (which is normally what would happen anyway... an honest professional will usually post their occupation at their website).
As for the impact of these bloggers, personally I do a lot of web searches to find out things about a product. It's perfectly possible for someone to find a blogger's page on some product and it influencing the person no matter how slightly. I don't know if there are any studies on the impact of viral marketing and such things though.
