4.45pm update: Who's news is it? Richard Sambrook, BBC global news division director, is among the panellists debating the merits, or otherwise, of open source news - otherwise known as citizen journalism.
2.20pm: One of the music industry's most enduring artists, Pet Shop Boy Neil Tennant, tells the Radio Festival why he believes a lot of radio stations are "corny and uninteresting".
Tennant is here to speak about the relationship between performers and radio, how important radio has been to the career of the Pet Shop Boys and areas in which he believes radio could improve. It's not often artists talk publicly about this side of the business, so let's hope he can illuminate us. As a former journalist, he should be able to find the right words.
Tennant is joined by Tony Wadsworth, chairman and chief executive EMI Music UK and Ireland, the label the Pet Shop Boys are signed to.
Radio 2's Jeremy Vine, the session host, asks Tennant who lets him down. "You could sometimes think commercial radio lets you down. There is an assumption when you have been making records for 20 years that your records are not as good as were. Our records have changed and developed, but people who would once A-list something won't any more because they don't think its cool. People are obsessed with doing things they perceive to be cool."
"Radio has played the Pet Shop Boys continually for 21years. If I was a radio station I'd be thinking what am I contributing as a radio station to creativity, to the community and I think the assumption that creativity is only going to come from something completely new, or that is a guaranteed hit, is a mistake - that is why a lot of radio stations sound corny and uninteresting."
So, it appears Tenannt does indeed have the words to explain himself, and he's not mincing them either.
"I don't think many radio stations take risks any more. Its safe to say that many [radio stations] think the new Pet Shop Boys record could not be any good, which is very cynical," he says.
Wadsworth joins in, unsurprisingly in a slightly more measured way: "The UK music industry is a very vibrant place and works best when it takes chances...I would say to radio - and I known its easier to say to the BBC than to commercial radio - if in doubt, take a creative chance because more often than not you'll succeed in that.
"The Artists I've done best out of are the ones that are further out there in terms of creativity," said the EMI boss. "I don't feel particularly let down by radio, but I do think we could all do better, record companies included."
But Tennant is off again telling the festival delegates where radio is going wrong. Blackmail, for instance.
"It's difficult to have a relationship with an ILR station," says Tennant. "The relationship that is developing as a kind of blackmail - that 'if you do a Party In The Park kind of thing we'll A-list your record'. So then you do the Party In The Park kind of thing and then don't A-list your record because they've lost interest by then. So a mistrust develops."
Tennant also promotes the idea that radio stations should be doing more to help unsigned artists: "Why shouldn't there be a relationship between young unsigned artist in Derby, say, and their local radio station. Why does it have to go through EMI house in London?"
And Wadsworth, surprisingly, agrees, and goes further: "I also question whether radio stations have enough specialist show as they should." He says specialist shows are a great way of road-testing material than could cross over to mainstream play. "A local station should give a number of hours per week to specialist shows from the local area. That's got to be a good thing."
4.45pm update: The flood of mobile phone stills and video footage sent by members of the public to broadcasters a year ago - on the day of the July 7 bombings in London - changed newsgathering forever. But is it a change for the better and can members of the public be trusted to report what's going on. And, how do broadcasters avoid being spoofed?
LBC breakfast show host Nick Ferrari said "the idea the traditional news media is gone is utter bollocks... the truth is we are in danger of being spoofed."
But the BBC's Richard Sambrook said there has always been a risk of being spoofed but what has changed is the technology, although the fundamentals of journalism haven't. "People have always tried to spoof the news, it has just become more difficult [to detect] because of the volume." But what has changed is relationship between broadcasters and audience, who now expect to be involved, he added.
Steven Nolan disagrees and says the term 'citizen journalist' is patronising nonsense. The public have always contributed to the news and we shouldn't put them off, says Nolan, with management speak and by questioning the public's trustworthiness. We should be looking at enhancing their contributions.
"I'm worried that as an industry we're going to have 20,000 management meetings about this...We've already said 'can we trust the public? But how many lunatics are there in the media?' Cue laughter for the floor.
About 15-20% of the content on Radio Ulster is listener generated, says Nolan, and after nine months on Radio 5 Live he is struggling to work out how best to use listener's material and tips on a national network.
Sambrook talks about the BBC's move from having BBC pre-moderated comments on its websites to post-moderated comments whereby the most popular comments move to the top. "And sometimes its uncomfortable, but if that's genuinely what's coming through then you have to respect that."
Delegates point out the importance of maintaining journalistic standards and checking and rechecking sources. One said the only thing that has changed is that national broadcasters have discovered what local radio stations have known for 40 years - that the public are key contributors to the news.
Ferrari concludes: "This is the most exciting and fearful time to be in the news business. The fearful side is citizen journalists who think they have to be daredevils. But if we police this it right, it will be fantastic. It's a great slave, but don't let it be our master."
