Journaling existed a long time before blogging. And for me at least, the old fashioned journaling, where you just write stream of consciousness stuff that you know will never be seen by anyone else, is a lot more liberating than blogging. Not only because you know that nobody else is going to ever see it, but also because of the writing technique usually recommended (just keep writing, don't edit, don't re-read, don't critique,etc).

I always found that blogging was just one more thing for my to procrastinate and end up not doing. :-(
