Why cant everyone adapt to the coding guidelines?

Just a note: I was looking back over the Style Guide and noticed, things listed in the Alternative PHP Syntax page, are actually listed as "bad" in the style guide. For example, using <?=$variable?> to echo something. That is used as an example in the Alternative PHP Syntax page, and then the same syntax is shown as Incorrect in the style guide under Short Open Tags. I'm guilty of this one.

I pretty much follow the style guide for everything else, not because it taught me, just because that's how I've always coded. If I had started differently.. I don't think the style guide would have changed me
