good question.
I have also come acroos these things while surfing the net.
Not a word of text or content,,, contrary to everything we've learned about Google.
The page is ALL links to more links to ,,,,, even more links!
i think it may be possible to simulate something like that by putting all the ads at the top of the page and putting your 'content' under the fold. has anybody tried this? as far as i can tell, there's nothing in adsense TOS that prohibits putting all the ads at the top of the page...
