Hey all, I'm in the process of developing a web app and was wondering what this community thinks of this idea. Is it ok to only target the latest versions of Safari and Firefox? Basically due to its lack of CSS3 support (and any other IE downfall). I've been thinking lately what's the difference between making a desktop app that comes with minimum requirements and making a web app have a minimum requirement. Or go the way of Apple with mobileme and put a disclaimer: "* Internet Explorer 7 is not fully supported. Internet Explorer 7 has known compatibility issues with modern web standards that affect Web 2.0 applications such as MobileMe. You can use Internet Explorer 7, but you will not have access to all MobileMe features and will experience slower performance."
