The multi-part articles are not good format for this website.

This may sound ironically, because we have the Sequences, etc. But when you read them, each article in the Sequences has its own point. If often references previous articles. But it does not rely on the future articles to provide its value.

Perhaps the second part will give some additional information. But it does not exist yet. The votes and the comments are about the first part.

When I think about it, the style you used here (and some other people used it in the past too), is the style typically used for books. The first chapter presents a big mystery, to make the reader interested. Then slowly we move to the solution. Like this:

• Why X?
• There is A.
• There is B.
• There is C.
• A and B and C imply X.

The problem is that the first part does not provide information, only a question. Even at the second, third, and fourth part, the question is still not answered.

This would be the Sequences style:

• There is A.
• There is B.
• There is C.
• A and B and C imply X.

It's almost the same as the previous, but the introduction is removed. And suddenly each article has its own point. The first article speaks about A. Not about "A as a prerequisite for some future X". Just: about A. Etc. The advantage is that each article can be enjoyed and discussed as it comes.
