The best text based web browser known to man. Lynx is very useful on any unix based computer because a gui does not belong on any unix based computers (except for all of the noob mac users who pay for freebsd...it is named FREEbsd for a reason...sigh), which leaves us with lynx.
my hosting customer has the most rotten pr0n site 3\/4r! zomg!!! *shudders...truly rotten! i do not want to be scarred for life by browsing his site where i can see pictures so i use lynx instead; it is especially useful when connected to the server it is being hosted on.
