As Inoshiro and streetlawyer have both pointed out, there's a lack of time and effort to get the knowledge needed to report properly - in all areas, not just technology.
I think it goes deeper than that though. the journalists can't be entirely to blame when the public doesn't care, either. And to be honest I don't blame either party.
Not everyone has an interest in technology the way that the majority of kuro5hin readers do. They don't want to specialise in it, they don't want to know the details about it, and they don't want anything thrust down their throat. They just want to know what they can do with it to make their lives better, and (possibly) how well it does the job.
To draw a metaphor, I am not a car expert and I really don't care about cars. If my car breaks I'll take it in to get it fixed, but I don't care how it works. I just want it to work and I don't want it to fall apart when I'm driving it.
If the mainstream media starts panicing about a batch of faulty tyres from some company, I might look up and get worried if mine match whatever the media's description is. I'm sure at the same time there would be many car/mechanical enthusiasts gloating about how it really doesn't matter because of X, Y and Z and I shouldn't be too concerned about the brand and batch number as I should be about some wacky specification I've never heard of.
I'm sure they'll say it's my personal responsibility to measure all sorts of crazy things of each tyre I get, correlating it in calculations with my vechicle's weight distribution to make sure that it's safe. They'll also categorise certain tyre manufacturers as dumb and stupid, catering with crap tyres to the mass tyre market.
To be honest, I prefer the media paranoia. It's simpler and it doesn't waste as much of my time. It's true that there actually are specialist auto journalists, but you'll find them in the car magazines... the same magazines I'd be reading if I had the slightest interest in the topic.
Yet, in an ironic way, I hope that the car enthusiasts will take it upon themselves to feel some responsibility. I hope that with their knowledge and interest, they'll put pressure on tyre manufacturers to make sure that ordinary people (who don't know or care what they're doing) don't get ripped off with shoddy products.
In conclusion, I don't think the media's ever going to get better. It caters to mass markets, and the only areas it specialises in are the serious minority that nearly everyone has an interest in. If you want good tech journalists, you'll find them in places targeting the technical market.. but nowhere else because other people aren't interested in reading them.
However, it doesn't let us off (as the technical audience) our obligation to do what we can to be concerned about technology in general, where concern is warranted.
