Alex Ben Block, the editor of Television Week and former editor of the Hollywood Reporter, will be on Larry Mantle's Airtalk tomorrow at 11 a.m. on KPCC to talk about "the growth of blogs as a form of news and how it's changing the rules of American journalism."

And in a potentially juicy matchup at this weekend's Times Festival of Books, Arianna Huffington, Hugh Hewitt, Ken Auletta and Geoffrey Stone will gab Saturday at 2 p.m. about the "Brave New World: Monopoly, Media and the Right to Know." The moderator will be the Times' David Shaw, whose recent column dismissing blogs as non-journalism is the object of much ridicule in the blogosphere and some media circles (and his argument in the column that LAT stories go through four levels of editing has been picked apart many times during the Eric Slater affair.)
