Yes I know, this is pointless pedantry, but this is nothing like the internet(a network of networks, the closest predecessor of which I can come up with is the post office) or even the web(a decentralized set of documents capable of being cross-linked) It is sort of like wikipedia(a centralized set of cross-linked documents) However, given the brevity of information you can fit on a card I would guess that it is actually a search engine(an index of decentralized documents).
