Air heads and Radio; Match made in HELL!

There is no dispute that our radio industry has blown up in a massive way and continues to stay on the top but I have some issues with the new kind of radio presentation.
Call in sessions used to be spaced throught out a four hour show such that a presenter had ample time to indulge their audience with the substance that's between their ears but sadly this is not the case anymore.
Do you that just about anyone can host a radio show and I mean everybody who can say this; "What do you think about that? Call us on blah, blah..."
Yes, that is the only thing you get when you tune to your favourite radio station and to be honest, it bores me so much I can feel my hair growing.
What happened to hiring presenters who pick a topic, a relevant one at that, and then tell us their side of the story or give us tit bits that helped us get our general knowledge sharpened?
Whether its a business deal with the mobile phone companies or just lack of content, radio listeners are being taken for a ride and many don't even know as they are busy calling in to hear how they sound on radio.
When was the last time you listened to a radio presenter and the talk did not end with you being asked to call in and give your two cents worth?
I have no problem with call in sessions but they should remain just that, sessions and not run the darn show from start to finish.
A presenter sees a picture in the papers or even saw someone crossing the road as they went to work; "Call me and tell me what you think about that."
They had a drinking session the previous night or are in a bad mood or got dumped; "What do you think? Call me and let's talk."
Why don't you just come and pull my hair dear presenter? Blondeness has been allowed on radio while all this time some qualified and interesting next big radio presenter is somewhere looking for a job with no hope.
Radio executives need to address this because at somepoint, you the listener will be asked to call in and just run the show and this I can bet you affects the quality of a show.
I know that to be a radio presenter is tough because but isn't that why very few make it on radio? The doors have just been flung open and every person who can talk with an accent is eligible.
