I don't see many folks here who've actually read the claims of this patent and analyzed them for validity. For all we know, this could be a legit difference over the art. But hey, claims are hard, let's go shopping. Or shame people, whatever.

The uniqueness of a variant on a linked list which I imagine many people have reinvented with variance over the years, is not important. These debates are meaningless because creating a system penalising people for creating something that solves their own problems with no external reference is being made a crime and hurting business. I myself have worked for companies who have had to spend years in legal disputes for trolls. It has a real cost. These people are a cancer and this is a tax on abstract thought.
1. This patent is on a variation that, as I mentioned in my comment, is very unlikely to ever be infringed when "people solve their own problems". Really, if you can think of a problem that that linked-list problem solves, I'd be very interested in knowing.
2. There is no tax on abstract thought. There is only a dispute if you make, use or sell infringing products. You are free to think whatever abstract thoughts you want. Given the vast majority of patents are a) highly specific and b) unlikely to be infringed anyway, it's unlikely any of your "abstract" thoughts turn into infringing products. Do you know of anything you've developed that has ever been the precise thing that infringed a specific patent?
