Hi Didier:
Right. The principle of rationality is a weak
predictor of human choice and behavior. Given
a choice in which one is pleasurable and one
is not, humans usually choose pleasure. The
Web, as we are taught, multiplied based on ease,
not technical merit. Still, the TAG is concerned
about warrantied behavior, and so has left the
domain of "What is easy and simple must be good."
That is why students are taught dharma; it
is the understanding of right choice that
over time, wealth is increased and then the
choices of pleasure are multiplied. But that
is the way of discipline, not because it is
gratuitous, but because it is sustainable.
Still, the scenario you outline depends on there
being web services the user desires to drag
and drop. Unless we build them, they have nothing
to choose from. If we build them, can we support
our own choice of choices?
I guess because my original markup grounding was
in the DoD community in which sustaining systems
for very long lifecycles was the problem put to us,
I still tend to think in those terms. I understand
some markets don't require that and purchase new
technology every three to five years without a
backward glance. I confess that today my thoughts
have had to turn to the ability to rapidly and
reliably hook up systems not originally designed
to interoperate, and for these, the idea that
one can tie a COM bag to the side, dump it into
the IIS directory and get a connection is very
attractive. We are in one of those, "waste
anything but time" periods of technical development.

Hi Len
Yep. If REST architecture could be as much as possible stamped "guru free",
made as simple as possible, then let the demand and supply do the rest (no
pun intented here, Nah... not true that was on purpose :0 ) In any cases,
the payoff should be clear and well grounded in realities. Simple enough
that that in just 30 seconds we can convince somebody in an elevator about
the merits of REST. I know, not easy. Now this time we have just to imagine
a guy opening a laptop, doing a drag and drop operation, writing a single
line of code and bang saying "see, I connected and used a web service". This
guy just showed "ease of use" in a couple of seconds. If, in contrario, we
have to bring the guy to the local "philosophical circle" to discuss the
merits of the technology for 2 hours at the least, then sorry, Len is right,
we've missed the target.
Hint: Economy of bandwith is not a strong argument. Economy of time or money
is. Humans are humans, tell them "what its in it for them" and they'll
repond.
