We're reaching out to a few of our top communities, hoping to get you on board with the migration to the new infobox markup. And we have tools to help!
Simply put: Most current infobox structure translates very poorly to mobile experiences, and indeed any device that doesn't use desktop-style displays. On desktops and laptops, they often look amazing. The problem is that Wikia's traffic is trending mobile.
There is an important graph from our forum post about infoboxes a couple weeks back.
Mobile is the future. Not just for Wikia, but for the web as a whole. Take a look at the recent trends and future growth predictions for mobile traffic - it's staggering.
We partnered with the Wikia community to create this new markup to make sure that your hard work can be displayed on mobile devices (as well as any future technologies) easily and without any new coding conventions. It'll take some effort up front, to be sure, but we're here to help, and the work you put in now will pay for itself tenfold in the future.
We've enabled two new features on your community. One is a tool for migrating the "old" infobox code to the new markup. It identifies templates on your wikia that look like infobox templates and places a box on the right rail of the template page. When you click the "Generate draft markup" button in this box, it opens a new tab containing a draft of your infobox using the new markup.
The second is a new feature on Special:Insights that will highlight which infoboxes on your wikia have not been migrated to the new infobox markup. It's fairly intuitive - you can click on the infobox title link itself to see the old markup, or simply click the "Convert!" button on the right, which performs the same action as the "Generate draft markup" button. Keep in mind the tool is not perfect, however, and false positives may be returned.
This is our help page for the new markup. If you'd like, I can help get things rolling by converting a template or two to draft form as an example, as well as watching this forum post for any questions that can be forwarded to the powers that be.
