One feature that Wikia has developed is the Mobile Main Page. It allows admins to change the default mobile view of the main page by changing the featured pages and content.
Advantages
- Design pages for the task - a mobile page for mobile users and a desktop page for desktop like tools
- No wikitext - The mobile main page can be completed edited without any knowledge of wikitext
- Mobile compatible
- Mobile editable - it can be completely edited using mobile devices without wikitext markup
- Pages automatically populated pages from categories
- Cropping tool
Disadvantages
- Some loss of control - apart from user selected pages the tool essentially shows other content based on how trendy they are
- No custom interface - mobile sites don't allow any css or js changes
The tool shows how some of the ideas here could be implemented without relying on too much markup or complicated interfaces. It even allows selecting a page image and description for each featured item.
