Well, I was going to chip in my $.02 about this, but Matt covered most of what I wanted to say. Hal Helms has written a book called Discovering CFC's, which is very informative. As Matt mentioned also, OOP is essentially the Defacto standard in programming now-a-days, and Macromedia is pushing CFCs and their usage very heavily. It would not surprise me if in the next major release (Blackstone or beyond) that Macromedia's standards for programming will be through CFCs exclusively.

As you might imagine that's a pretty big question. :-) I'll try and
gather up some resources and send them out, and then we might want to
hit this at a future meeting. Even though CFMX has been out for quite
a while now I suspect there are a lot of people in your situation, and
honestly it does get pretty detailed pretty quickly to truly
understand the concepts behind using CFCs. They're easy to get going
with, but there's no one-line answer that would address your other
concerns without a bit of background first.
At a high level there are several reasons to use CFCs, and in many
ways these are the same reasons you want to use some of the other
methods we're all familiar with (UDFs, custom tags, includes): code
reuse, better code organization/lack of spaghetti code, etc. What
CFCs open the door to, however, is the world of object-oriented
programming (OOP), which if you come from a procedural background can
be a bit of a learning curve. People have argued (even on this list
not long ago) over the advantages and disadvantages of OOP, but the
computer programming community as a whole has more or less spoken on
this topic, and OOP is now a de facto standard way of programming.
Also bear in mind that OOP has been around a LONG time by this point,
so the fact that we as CFers are just now jumping on board means we
have some catching up to do.
I wrote a blog entry based on a presentation Hal Helms gave at the
CFUN conference this year, and it got picked up on the ColdFusion
Developer's Journal site. Since it was originally a blog entry it may
be a bit less formal than I would have made it as an actual article,
but I stand behind the sentiments:

You might also want to go straight to the source and check out Hal
Helms' own web site:

I personally think this would make a great topic for a future meeting.
We've talked about CFCs at a technical level (how they work, what
they do), but I think without a deeper understanding of the why behind
CFCs, people may have trouble getting on board with them.
I'll ponder this and post as I remember other resources, and if others
have interest I think an OOP/CFC meeting in the near future would be
great. Actually it would fit pretty well in February with the other
speaker we have planned.
Hope that helps a bit,
Matt
