For Zero users, when visiting m.wikipedia.org, we have to show a custom start page tailored to the specific mobile provider. A typical startup page has a custom banner, e.g. "Free Wikipedia provided by [Company]", and a list of common languages in that country. The language of the page is always set to the provider's default language.

A partner suggested that we add some additional text on the startup page, as otherwise the page looks empty and not very inspiring. That text would be an HTML blob, similar to the WWW page, but significantly smaller due to most devices having a tiny screen. The text would be different depending on the default language set by the provider, and could also differ between various projects - Wikipedia vs Wikinews. The text would be stored on translatewiki, with the overrides residing in the project's MediaWiki: page.

The text could be a one sentence "welcome to {{SITENAME}}", it could be some famous quote, a news item, word of the day, link to featured article, or anything else the community may decide to post. See sample screenshots for Android, iPhone, iPad)

What would be the best process to maintain that text? What other possible customization would be needed to make this beneficial? Please keep in mind that most of the users coming to this page will be directed there by the carrier advertising Free Wikipedia, so a lot of new users.

P.S. If you think this discussion should be on meta, please let me know of the best location.
