Here are a few blogs I've discovered recently. Rather US-centric, I'm afraid:
Charles Apple - Charles is "a freelance visual journalist and instructor". I think there's an increasing need for every journalist to be, to some extent, a visual journalist. And I'm not just talking about page layouts.
Grammar Monkeys - language podcasts from the copy desk on the Wichita Eagle.
The Blood-Red Pencil - fiction-writing tips from a whole host of writers. A lot of the advice is relevant to other forms of writing.
Behind the Grammar - posts about "business, marketing, podcasting, writing, and life" from Grammar Girl Mignon Fogarty.
The last two are in my blogroll and I might put Charles Apple there too, if he behaves.
