I really liked being able to keep a written journal; when I was writing in that, I found that I was thinking more about the content of what I was writing and it was much more personal. I would include a lot more tangents, anecdotes, and doodles that I have trouble incorporating into my online journal. I feel like when I'm writing something (especially when I know that anyone can read it) I try to make it a lot more polished and I end up taking a lot longer to think of something to write about. In previous journals, after doing that day's reading, I would just write down whatever I was thinking about, even if it wasn't totally relevant. I had a lot of fun doing that kind of writing, and I know that keeping a written journal has been an option, but I would always feel guilty because if I had enough free time to do that, I felt like I should be working on my online journal or an upcoming paper instead.
I don't know that getting rid of the online journals altogether would be a good idea, because I think that some people have definitely benefited from them, but I wasn't really a huge fan of them.
