I'm not talking about re-hashing Wiki content, Dave. Blogs are personal. Topics could range from "How I found FET" to comparing and contrasting infinite plane vs monopole, in your own opinion. It'd also be a good place to showcase some member-run experiments, small scale type stuff. I live in the mountains which makes Bedford style experiments impossible, but I'm sure I could derive an experiment or two to conduct, particularly in the summer when I'm not buried with school work.
Also: what Rama Set said.
