Now it's called blogging. Xanga -> LiveJournal -> Tumblr.
Personally, while I do blog periodically, my journal is entirely different than what I publish online. My journal is for my own consumption. Some things that are written down there (I prefer pen and paper) may end up online or in an essay, but others won't see the light of day (often for good reasons).
Other than that I'm not sure what we're arguing about. Though it is interesting you have things to hide.
