The really tough barrier is getting enough people with the required expertise to do the annotation.

Annotation sites like to say, "Hey, we have this paper and we have this paper." Meanwhile, thousands of new scientific papers are published every day. Of course, the majority of those are not going to be of interest to any journalist. But even when we whittle the pile down to those that are, there is still a huge amount of work to do, and some qualified person has to do it.

And why would they do it? I'm an academic researcher. So I have the required expertise to do this kind of annotation for papers in my narrow specialty. But my life is full with my own research and publishing and teaching and advising and committees and paperwork .... And every October I have to write up a report on my achievements for the past year. Getting a paper published counts for a lot in that report. Annotating someone else's paper is not going to count for much at all. If I start substituting the latter for the former, then my career is going to go down the tubes pretty rapidly.

I think it would be great if this kind of thing could actually happen. But I don't see how to make it happen.
