A
socially inept person who dwells on the internet because he doesn't have much to do in real life. They often hang out with other internet dwellers in online forums, message boards and other
social networking websites, creating many diverse communities.
Not to be used to describe a person who simply browses the internet a lot, as internet dwellers also tend to stay away from the more mainstream
social networking sites and only browse the more obscure corners of the internet, like what a real-life dweller would do.
