I think this is a great thing you’re doing, bone. It’s not scientific, but at least it provides something to get some kind of read on defensive gun uses. And so far, reaching back to August, you’ve got like 8 incidents or so. Slightly less than one per week. That’s great!
Of course, GunFAIL blog, using the same process (reviewing stories in the media) finds about 50 incidents a week. They don’t include homicides or intentional gun crimes - just times where people fucked up with guns.
