Nancy Friedman runs a verbal-branding consultancy called Wordworking, and contributed today's "Candlepower" column on naming. She suggests these blogs on language, branding and media:
Wordmall. "The labor of love of retired English teacher Michael Sheehan (who also contributes to the excellent online magazine Vocabula.com). Each post takes a familiar word or term -- one of my favorites is "bogus" -- and examines its history, etymology, and usage."
The Language Guy.
"The lessons of linguistics applied to advertising, journalism, politics, and society. Written by a retired linguist, this blog is invariably well researched and feisty."
