Commenting your code is very important. Everybody knows that they should, but how many people actually do it? When I’m trying to fix a WordPress syntax highlighter plugin, there are no comments in it to guide me. I have no experience writing WordPress plugins, so without the comments, I don’t know what to fix. That’s why I’m working to learn how to use the Worpdress API so I can write my own syntax highlighting plugin. With comments, the lives of other people are easier.

Just a reminder.
