Yes, PACER is an uwieldy system. Thanks for mentioning that paper. I look forward to reading it.
Unfortunately, the systems in many state courts is far worse. I've visited the web sites of all or most all state high courts and while there is a lot of variation, some are just awful. In many states there's just about nothing there in terms of what cases the courts are considering for review, what cases the courts have accepted for review, or when the courts will hear arguments in cases they've accepted.
This report is encouraging. Also, those are excellent points about how reports like this one come up a bit short in providing a full picture of things. I too hope others will look more favorably on the self-regulation we are seeing with video gaming.
