Get over yourself. The guy wrote something that suited his own needs and released it so that others could use it too if they wanted. Programmers ported it to other languages because they liked the idea and wanted to see it thrive -- I've used the PHP port in many homespun web apps over the years. Is it perfect? No, and no software is. But when I've needed a script that easily converts line breaks and hyphens into paragraphs and unordered lists (the normal use case I've taken advantage of), it's done the job every time.
