I modified my Movable Type template to display a small graphic associated with the subject (category) of an posting next to its title. Those who are uninterested in my technology writing can avoid postings with a CD next to the title (as shown with this posting); those who are uninterested in politics, can avoid that graphic, and so on. (My friend Chris at Empty Bottle also uses graphics to designate categories. However, his graphics are a lot more sophisticated than mine.)
I thought about creating multiple weblogs and focusing each on a different topic, but I wouldn’t write more (or less) on any subject just because I split them out into different weblogs. All I would do is scatter my thoughts about like dried bits of corn on a dusty field, forcing my readers to take on the visage of Crow, pecking about hoping to find that edible kernel among the dirt.
Besides, my thoughts don’t split cleanly along subject and topic, neatly categorized into discrete buckets. I’m just as likely to throw new photographs or a bit of writing whimsey into an essay on RDF, or mix a little technology into an essay on the Environment. My weblog reflects my writing, which reflects my mind: muddied waters of blended interest.
