A group of companies is proposing the creation of a new Internet top level domain called “.mobile”, with rules that require sites in .mobile to be optimized for viewing on small-display devices like mobile phones.
This seems like a bad idea. A better approach is to let website authors create mobile-specific versions of their sites, but serve out those versions from ordinary .com addresses. A mobile version of weather.com, for example, would be served out from the weather.com address. The protocol used to fetch webpages, HTTP, already tells the server what kind of device the content will be displayed on, so the server could easily send different versions of a page to different devices. This lets every site have a single URL, rather than having to promote separate URLs for separate purposes; and it lets any page link to any other page with a single hyperlink, rather than an awkward “click here on mobile phones, or here on other devices” construction.
The .mobile proposal looks like a textbook example of Lessig’s point about how changing the architecture of the net can increase its regulability. .mobile would be a regulated space, in the sense that somebody would make rules controlling how sites in .mobile work. And this, I suspect, is the real purpose of .mobile – to give one group control over how mobile web technology develops. We’re better off without that control, letting the technology develop on its own over in the less regulated .com.
We already have a regulated subdomain, .kids.us, and that hasn’t worked out too well. Sites in .kids.us have to obey certain rules to keep them child-safe; but hardly any sites have joined .kids.us. Instead, child-safe sites have developed in .com and .org, and parents who want to limit what their kids see on the net just limit their kids to those sites.
If implemented, .mobile will probably suffer the same fate. Sites will choose not to pay extra for the privilege of being regulated. Instead, they’ll stay in .com and focus on improving their product.
