In response to some blogfight I don’t really understand or care too much about, Choire Sicha published a handy guide for determining whether you are on the internet or not.
Sometimes it’s hard to tell if you are on the Internet or not. For example you are almost always typing into a box on a series of screens on your computer. Because of this, there are whole sections of the Internet that are pretty sure they are not on the Internet, because, they are just boxes, right? You could be typing into anything, who knows if it’s public. This was true about LiveJournal for a long time. When you would link to a posting on LiveJournal, back in the day, you would get outraged emails about invasion of privacy. Because in their minds, they were just typing in their diary.
