Thought of the day. Let's think about links as currency people use to trade thought capital with one another. That way, we can explain the growing homogenization of the Net - inflation.
Link inflation: The growing number of links chasing a (relatively) smaller and smaller amount of thought capital. A smart entrepreneur would attempt to arb the differential by establishing an alternate currency - not just hoarding links like link aggregators (blogdex, daypop, etc) do in order to preserve value. I don't mean something evil, like MS's doomed SmartTags - I mean a tradable currency which doesn't get devalued like links currently are.
