While I see the use of voicetracking, I think your description of those who find it distasteful as "third-tier radio talent who maybe lost their employment due to voicetracking" is a bit insulting.
I understand the financial benefits. I understand most of today's jock content doesn't benefit from a live body in the booth.
HOWEVER, I guarantee that a voicetracked jock will, by necessity, be less engaging than a properly performing live jock. If that live jock is monitoring local scanners and news channels, if that live jock is taking live calls for things like traffic, if that live jock is tracking storms moving into the area...
That, also, is that hyper-localism that you're talking about. Sure, it takes more money. And yes, it is a greater risk, both that the live jock won't justify his cost and / or that a personality of that strength might take their audience across town... but success could be VERY big in this sort of situation.
One of the most fun things I ever heard on the radio was maybe 20 years ago, long before Facebook or Twitter or texting, when a CHR did a countdown every night and EVERY break was a different listener announcing the next song on the countdown.
You're right that the listeners are key to a sucessful radio show. You're wrong that voicetracking is the best way to achieve it. That is, in fact, the most difficult way to do it. You have to set up voicemails, etc to record the listeners, then the listeners don't hear themselves on the air until what, the next day? The next week?
Attention spans today are WAY too short for that.
Before you ask, I am happily employed doing afternoon drive at a popular station. I'm live; our morning show is piped in live from another time zone.
Please stop bashing out-of-work professionals in an attempt to justify the "saving costs at all costs" of today's radio. All you're doing is giving yourselves an "At least we're not like THEM" ego stroke. It's tacky, and I'd hope you'd be better than that. You're not helping the unemployed with your ugly comments, either.
