I’ve been meaning to post about this for a few weeks now – Tom Coates of plasticbag fame has been blogging about the BBC annotatable audio project. The widget being produced will allow text comments to be added to audio, so if say you were listening to an item on the Today programme you could comment on that article and people using the BBC radio player can then see your comment. Other stuff can also be attached to each segment such as transcripts, contact details etc.
Sounds like a great idea, digital TV has transformed how information can be delivered about a particular TV show and radio would really benefit from something similar.
