Probably people out there who don't remember that "blog," comes from "web log." Some are commercial, some offer useful information, some opinion.
Ten of the links are martial arts related. (Others are by martial artists, but this subject isn't the majority of their content.) Four are primarily for and about writing. The others are commercial, news, general opinion, and -- a nice word from crossword puzzles -- olios.
Some of the sites are attended to regularly -- postings ranging from daily to every few days. Some bloggers -- there's a word that didn't exist a few year ago -- manage a post now and then, and it might be weeks or months between them. Mostly, if a blogger stops being active, I let the link stand for a while and then remove it. I figure that if nothing has been put up for six or eight months, the writer has moved on and and isn't apt to be doing much else with this particular effort. Sometimes I leave them up because the writer will have links that are still useful. When I can, if I find another site done by the same folks, I'll link to that.
If I have a gripe about personal blogs that I offer in my list, it's that most of them don't write often enough.
You guys need to get on the stick.
