Paper or plastic?

I'm not talking about the famous question asked at supermarkets nowadays. I'm talking about journalling. :)

When talking about your deepest, darkest, most personal thoughts, do you prefer the good old-fashioned paper and ink journals, or the modern way of going online and typing your thoughts out for an audience (or yourself, if your journal is private?)

What do you think are the advantages and disadvantages of online journalling, as opposed to paper and pen?

Do you tend to hold back in your online journal for fear of ridicule or criticism? How about your paper journal? Do you hold back for fear of someone finding it and reading it, or do you just let it all out?

I'd love to hear all of your thoughts and views on this subject! :)
