There are two semantic phenomena made prominent with the advent of tagging:

1. We use related words to describe a concept wrapped in a point-of-view.
   If memory serves, in his Ontology is Overrated presentation Clay Shirky uses “film”, “movies”, and “cinema” as an example. Each of these words describes similar, but different things.
2. We use the same word to describe vastly different concepts.
   Take “java” for example it could be referring to coffee, code, or a country.

Surprisingly, Google, Yahoo, and MSN haven’t yet connected people with their points of view. Dave Winer suggests:

“Let me tell [search engines] where my weblog is. Then it knows what my interests are. Give me search results relevant to who I am.”

Reminds me of something I wrote about on why Google Adsense doesn’t work.

Whether it’s the words in this blog or other sites I’ve read – I’m implicitly declaring context and point-of-view every time the browser refreshes. Then it goes straight down the memory hole.

(What I’ve looked at before + What I’m looking at now) / What you’re trying to tell me = Targeted ad

Excuse me, could I get a refill on the Attention Kool-aid?
