New blog?

Friends, you should all know by now that I will be pursuing a career in journalism. I want to sharpen my writing skills (and perhaps attract readers) with an opinion blog; my question to those few of you who read this one is - what would you be interested in reading? I'm looking for a niche to write in, not necessarily political, though I suppose that'd be a good diving board for my field, and I'm just curious. I'd appreciate your opinion.

(Also, would any of you CS geeks be willing to help me set up a domain and a website? Or let me use your Dreamweaver? :D)
