We're at the turning point where great journalists are getting pushed out of their careers because jobs are vanishing under their feet. The content model has completely changed, some argue for the better. In the long term I fear the quality of content written will suffer, article accuracy will be reduced and we'll all be reading each others blogs about medicine [insert other topics here] (without ever having studied it or any previous knowledge on the subject). The Internet of "everyone's an expert" overnight is not something I'm looking forward to. Just look at all the overnight social media professionals. Many of these people don't have an understanding of how the Internet (or email) even works but they'll throw down the hot keywords to make themselves sound important; KPI's, User experience, etc etc.
I still feel there's huge opportunity in the learning space for online education. If I was a journalist or writer with specialized knowledge in a certain field, I'd focus my attention to that and bring my friends.
Journalists job is not to know about the thing they are covering; usually they have only slightly more knowledge than the layman; their job is to have relationships with people who can give them information the public doesn't easily have.
These relationships that lead to information becoming available won't and isn't going away, the people doing the reporting (now called bloggers) just aren't getting paid (much) for it. It's now a hobby. And that's ok.
As far as writings from experts; science journals still exist and AFAIK are not hurting or are in danger of being scaled back. Maybe someone with more knowledge can speak on the state of academic journals.
