I have seen and heard shows about good grammar in Portugal, but nowhere else. Recently, I found Klare Taal from RNW. Hosted by the congenial Arie Bas, the program talks about how different words are used. He also talks about Afrikaans.
I passed through the Netherlands once in 1985. While I don't rule out another visit, such an event is unlikely. Other than this project, I have no connection to the Dutch speaking world. I'm currently learning Dutch through the media and reading DE EEUW VAN MIJN VADER (My Father's Century) by Geert "Big" Mak.
