1. Geektronica has a post about the unfortunate phenomena of spam blogs on blogspot. I tried clicking the "Next Blog" button in the upper righthand corner of my blog. Sure enough, about 1/3 of the blogs I found were spam. Oh well.
2. I searched for blogspot blogs which list Bozeman as the site location. A large fraction were way out of date and seemingly abandoned ;-(
3. Conclusion: the best way to find blogs is to follow someone's blogroll. For instance, see the "The Big Sky Blog" blogroll on the sidebar.
