An anonymous reader calls to our attention a blog post about the way the iPhone's multi-touch UI will strain the interface conventions of Web 2.0. This looming clash comes clearer as Apple releases more details of the iPhone's UI. Much has been made about the iPhone including Safari to provide a full web browsing experience. But this reader is wondering how compatible certain sites will be with the iPhone's input. From the post: "[Web 2.0-style interaction] makes somewhat heavy use of 'onmouse' events and cursor changes... along with CSS a:hover styles. The iPhone challenges those particular Web 2.0 conventions, though, because it is a device that not only adds support for another pointer, but at the same time eliminates them as interface objects... [T]he user doesn't get to express their attention with the iPhone... They only get to express their immediate action." This reader asks, "What other pitfalls lurk in the multi-touch web? Do any Slashdot readers plan to adjust their sites to ensure they work with the iPhone, and can you think of any similar issues that will crop up with such a different browsing experience?"
