A very good sentiment. I'll have to remember that.

I've had a not-so-dissimilar experience myself but I believe it's my
own limited vision of their place in an application that is probably
causing much of it.

Ah, opaque proxy objects. :-) This has been my biggest complaint,
but the situation has much improved in 10.5

I'd be interested in hearing this as well if it exists. I know mmalc
had traditionally been "the authority" on Bindings, so maybe if we say
pretty-please, he could offer some additional tips.

You just *know* that when you make such a blanket statement, some
smart-ass is going to ask you to cite specific examples. I would be
honored if you'd consider me that smart-ass. :-)
