These articles are useful for people such as myself, who perform a majority of their work on intranets. With companies making the common-sense decision to stick with one browser internally (and given that many go with the Windows pre-installed IE) these articles do have justification.

Also, as stated in the article, this could become a standard in the future, so getting to know the details now just makes good professional sense. The concept behind it is sound and *useful*, so I am crossing my fingers it does make it into the next round of official specs.

PS : I agree that internet-based sites should be written to current W3C standards and any web designer who doesn't understand why should lose their "License To Code" (hmm .... now there's an idea!).
