Writing about the 25 most valuable websites is very clever. Not including one single link to a mentioned site is not.
And it's a good article, but not linking to original sources on the web makes publishing on the web pretty pointless.
I came to the article from another website but I know some publishers are reluctant to link away from their own site. Unless it's another site of the same media brand.
This is de-enginering the web back to, well, what? Something less than useless. How would you find anything?
You can swat flies with a paper when there is no more information to be had.
But like I said, It's a great article so don't let me hold you up (lnk)
