Mastering Regular Expressions
RegEx is supported in all major development environments (for use in editing and working with code) and will thus appeal to anyone using these tools. In addition, every JavaScript developer should be using RegEx, but most don't as it has never been taught to them properly before. Developers using ASP, C#, ColdFusion, Java JSP, PHP, Perl, Python, and more can (and should) be using RegEx, and so every one of them is a potential reader too.
