Skype & News
I've been keeping at eye on Skype over the years and until recently thought that the quality was just not up to a standard useable on TV. I've been doing some testing over the past few weeks and now think it's at a stage where it is useable. That said however we will always be relying on the contributing viewer having.
I still don't see that Skype can ever be used for competitions, but for a comment style service where we can vet the callers, it could work well.
