Over on the BBC editors blog Steve Herrmann
When is it acceptable for us to make use of personal pictures and video available on the internet?
With the growth of social networking and personal websites, it has become far easier for the media to get hold of such pictures. If we do use them, can this be justified?
I have a rather objective opinion on this. Anything published on social networking sites,is to me in the public domain and therefore its use can be sanctioned.Those that are published on personal well that is a different matter.There is a public interest issue which can overide this but in genreal terms permission should be asked.
Finally as Steve points out
The boundary between what's public and what's private isn't always easy to define online, and I think it’s also true to say it’s not something people always give a huge amount of thought to when posting.
