Maybe I'm the one missing something

Magicians make a living at misdirection, getting you to look at their right hand while they're hiding the ball with their left hand. You'd think journalists would want to be a little more direct than that. But Neil McAllister did a whopper of a slight-of-hand recently, using more than half his column to summarize a Joel Spolsky post before jumping to a completely unrelated conclusion.

Joel's point, and the first more-than-half of Neil's summary, was shooting down the idea beloved of suits that programming can be reduced to a set of building blocks that can be snapped together by a non-programmer. (For a hysterically painful example of how wrong this is, and how far people will go to try to do it anyway, see The Customer-Friendly System at The Daily WTF.)

Joel covered the ground pretty well, so I was wondering where Neil was going with this. Once I got to it, I had to re-read the segue three times to see what connection I was missing:

Don't you believe it. If, as Brooks wrote, the hard part of software development is the initial design, then no amount of radical workflows or agile development methods will get a struggling project out the door, any more than the latest GUI rapid-development toolkit will.

And neither will open source. Too often, commercial software companies decide to turn over their orphaned software to "the community" -- if such a thing exists -- in the naïve belief that open source will be a miracle cure to get a flagging project back on track. This is just another fallacy, as history demonstrates.
If there's a fundamental connection between open source and "Lego programming" I don't know about it. Maybe Neil makes the connection for us:

As Jamie Zawinski recounts, the resulting decision to rewrite [Netscape's] rendering engine from scratch derailed the project anywhere from six to ten months.
Which, as far as I can see, has nothing to do with the fact that it was open source. In fact it seems more like what Lotus did when they delayed 1-2-3 for 16 months while they rewrote it to fit in 640k, by which time Microsoft had taken the market with Excel. Actually that's another point that Joel made, sooner and better.

Is Neil trying to say that Lego programming assumes that code can be interchangeable, and man-month scheduling assumes that programmers are interchangeable? Maybe, and that's even an interesting idea. But that's not what he said, and if I flesh out the idea it won't be in the context of a critique of someone else's work.

Or maybe it was an opportunity to take a shot at the idea of "the community". Although in his very next column he talks about the year ahead for the open source community, negative community reaction to the Novell/Microsoft deal, and praise from the community for Sun open-sourcing Java. Does he really dispute the existence of a community, or was it hit bait?

Okay, so where did I start? Right, with misdirection. So the formula seems to be: quote a better columnist making a point that I like, completely change the subject with the word "therefore", summarize another author making my second point, and send it to InfoWorld. Am I ready to be a "real" pundit yet?
