Glen Reynold's current TCS column covers picking a subject as part of the process of becoming an influential blogger (in his words, a blogging bigshot). In short, find an empty niche, fill it, provide original content is his advice.
It's pretty good advice. One of his thoughts was municipal blogging, but municipalities are not the only political jurisdictions that are under-covered. You can also cover a metropolitan area, a county, or a state which will give you more material to work with.
Also, if you're going to branch out into a nontraditional format, the idea of using audio and video aren't the only options on the table. Maintaining a database of information on your chosen specialty or publishing a wiki are two further alternatives.
