"An 
opinion is a 
person's 
ideas and thoughts towards something. It is an 
assessment, 
judgment or 
evaluation of something. An opinion is not a 
fact, because opinions are either not 
falsifiable, or the opinion has not been proven or verified. If it later 
becomes proven or verified, it is no longer an opinion, but a fact. Accordingly, all information on the web, from a surfer's perspective, is better described as opinion rather than fact."
