Here are a few online language-related resources that I came across recently:

- A series of videos on YouTube showing how Chinese characters have developed from the original pictures:

- esPodkasto - la podkasto en esperanto (Esperanto podcast)

- Lojban Radio - an introduction to this logical language (in Lojban and English)

- Hour of Babble - podcasts about constructed languages (conlangs)

- Eddie Izzard on learning French
