Please keep it "journal" instead of "blog" ... because
1. Blog is a more internet savvy term that not all users will relate to
2. The nature of a blog is to publish to the internet ... and since the present journal system allows for totally private entries the word journal can be more readily interpreted to mean a "blog" OR "diary", "project", etc... the kinds of things one might expect to keep "private" rather than "published".
3. With everybody and their brother offering "free blogs" to users, the word "journal" seems to add an aire of distinction to our boards.
4. This is just my opinion.
5. Thanks for your work!
