Tagging pictures, and other things like videos, has become a hobby for some people. I have been tagged from ugly pictures of me during times-I-want-to-forget to pictures of the newest POS systems available in the market these days.
Ordinary people use facebook to communicate with families and friends. Businesses use it to make people know of their new products and services. Tagging is really not that bad. But facebook users should be responsible in tagging other people.
