Open Diary
Open Diary is the first known blogging site, which predates Live Journal.
Open Diary was never particularly popular, however, and in internet terms it is often forgotten.
Open Diary was not particularly user friendly, as it only allowed people to see one post at a time, not the entire thing. It also required passwords to view posts, did not easily enable comments, and writing it was also quite difficult.
Once Live Journal began, and was far more user friendly and had many more things that could be done with it, Open Diary was soon ignored in favour of it.
