One of the many advantages of paid posting is that you learn new things. If you are a blogger, then some of your posts are compensated by a company or a website owner. Most of these articles you write will be about their products or services. One interesting topic I've received is a form of " biotechnology ". Specifically, it is under the category of "Red Biotechnology" which generally speaks of application of technology in the field of medicine. One such application is the Cochlear Implant . Another term for this would be the "bionic ear". A Cochlear Implant is an electronic devise that is implated to the the ear of a person with hearing disability.
