Thread:Extension talk:SmoothGallery/Garbage Text In Section Headers / Incorrect Page Title/reply (5)

The   tag just seems cleaner and easier to remember how to use than using the parser function style. That being said, people could always learn how to use the parser function version if need be.

The main issue though is that if showinfopane isn't set to false, there's all kinds of garbage text that shows up in the section headers and the page title gets changed.
