Maybe.  Sometimes it is worth slowing a process down, but that 
should be built in and not a side effect.  Do remember the Thule 
Greenland incident in 1960.  Had the process been running in 
machine time, North America and most of Europe and Asia would 
still be cinders.  Humans should stay in the loop.

Because setting up a web service takes a certain amount of 
savvy.  Almost any idiot can build a web page and plant 
references to toss google a curve.  Sure, that 
is the idea, but it means we have to vette sources and Google 
being somewhat uncaring or laissez faire (as it should be) isn't 
always a trustworthy source.  One pays for quality and it may 
be the case that for some kinds of information, one will pay 
to ensure it is vetted.  Yes that is a stratified web.  Yes 
it is happening and inevitable, IMO.  One aspect of the semantic 
web could be the detail, consistency, and verifiability of 
such promises.  This is where the semantic web and web 
services have mutual interests:  reliable assertions.

Easy for thee.  You are not the average bear.  Obscurity is not 
security and difficulty won't always make things less likely, 
but likely to make things less likely.  What the article 
showed was the ease with which one could game Google.   
At one point, it was suggested that what Discovery 
systems were proposed for (eg, UDDI), Google could do.  Google 
can but the results are worth about what one pays for them.

Therefore, caveat emptor.
