Wireless Wonders: Podcasting and don't say 'um' (or is it 'uh'?)

Rob Griffiths at Macworld, in his assessment of podcasting, is also disturbed by those what-do-I-say-next "um", or is it "uh", sounds?

My friend and fellow Macworld author Kirk McElhearn has put together Kirk’s Seven Rules of Effective Podcasting, which is a great place to start. It’s probably not all-inclusive (I would have included “Don’t say ‘uh’ even once” as Rule No. 1), but it’s a good list of things to consider if you’re thinking about podcasting.
