It would be a good idea to change all English special page aliases to common spelling, i.e. "Broken redirects" instead of "BrokenRedirects" and so on. Most people aren't used to read words like this and instead stop reading at a space. Furthermore, it's quite confusing when the title says "Broken redirects", but Special:Broken redirects doesn't lead you there. The old camel case should probably be kept for backwards compability, but IMO the default title of a special page should be changed to proper spacing and casing.
