The blag. Not to be confused with the blog. (Blags are the journal-esque things written on random topics: all blags are blogs, but few blogs are blags.)
Blags are intentionally written without plausible sequence or order...most of the time, anyway. They truly are just expressions of what's going through my mind - a call back to an older Internet perhaps, when private journals became ever-so-slightly public. Topics are often personal, and structure varies...sometimes rambly and loose, othertimes written more like an off-the-cuff essay.
All in all, good writing practice.
