I did mention Java might be an exception - but the implementations have
been really lacking in performance. Honestly, when was the last time
you saw a really useful (cr)applet? Plus, Java is a good example of
how not to do an OO language.
I looked at UIML and it looks like a bad joke to me. I can't remember
when I've seen something less readable and more complicated that did so
little. So much noise for so little signal.
Your later comment about hammers is particularly applicable. ML's are
really poor mechanisms for describing behavior. They're sort of poor
mechanisms for describing relationships (they impose a sort of
directional view via the element nesting that is artificial - is artist
inside of CD or is CD inside of artist - depends). They're not bad for
describing elements in streams. Sadly, the "well formedness"
requirements in XML makes them not particularly good for general
"markup" as well. Markup (think red pen) is more free form than that.

You ought to spend some time doing WebObjects development. Because
XBL also looks like a mishmash of Java and XML and is overly verbose
and unreadable. I'm not too impressed.

Are we talking about application delivery over the web or not? Because
you have to question the underlying assumptions and examine the
evolutionary path that lead us to this location. Failing to consider
that is to blindly accept that things are correct because thats the way
they are.

I do too. Sadly, we've stripped the behavior off of the data now. Its
still inanimate - whether its xml or result sets, the data is still
passive. I don't see this as progress.

Examples? I don't see one. If I did, I'd use it for developing the
latest web based house of cards my client wants.
