Speaking of perfectly targeted ads.
Here's a screen shot of a NYT article about Raymond Felton of the Knicks.
And in the right margin an ad for a tech conference put on by O'Reilly.
I would put in my profile something like this: "No more offers of tech conferences that don't include speaking offers."
That would be what Doc Searls calls a "conversation."
We're getting closer.
Reminds me of a story about me, John Doerr, Google and Philip Bump.
A long time ago I wrote a story about John Doerr, and it ranked very high on Google in a search for John Doerr. I joked that my investment in Doerr was doing well. As if "owning" him on Google had some dollar value.
Philip Bump, a clever dude, bought an adword next to that search, knowing that I would look at it, and the ad said "Hey Dave Winer..." I laughed. But that's as perfect as targeting can get. He had a market of one. And I actually did see it and loved the attention.
He now writes for The Atlantic, and he told me the story when I went down there to visit last year.
