I have now added to my front page: Legalesed (law, language and leftovers) and Working Languages (legal translation and interpreting), which now permits comments without registration.
TranslationMaven by Matt Elsworth (profile here) is one I have missed (thanks, Trevor).
Carlos lists more new Spanish-language weblogs on literature and language on Las palabras son pistolas cargadas (this mentions TranslationMaven too).
