Food is used in a variety of ways on the internet. while there are some foods that are better than others (such as how tacos, bacon, and cake) there are also foods that present a negative connotation on the internet (potatos). Some of the more notable examples include Cheezeburgers, which were made popular in 2007 when Eric Nakagawa created a www.cheezburger.com. Since the creation of the website food has been heralded on the internet.
For reasons unknown (most likely because they are delicious) foods such as Tacos, Bacon, and Cake have been considered the best thing to ever dawn upon mankind. With Potatos being a notable example of food that is just plain terrible.
