I only lately realized the distinction between a journal and a blog. A blog (or weblog) is an ongoing link-list with some commentary, while a journal is a full-blown diary, with or without links. (Any blog-veterans out there, am I getting this right?) As for me, I often switch modes: sometimes I post lists of links, sometimes just personal diary entries.
I guess that makes me… a jolog. Um, never mind. I think I can settle for “blog” as a general catch-all term.
