I didn't think of that. You're right -- knowing your users' background and knowledge is very important. However, there are things that I believe simply shouldn't be carried over from desktop to web. Even in desktop, modal dialogs reek of "I don't know or care how to do it better". Double clicks have a similar feel to me. And neither is much present on the web (1.0 and 2.0). Even GDocs don't rely on double clicking (though they try to mimic the Office behaviour in other ways). But sure, if the users never really used the web and are used to desktop tools, it would be easier for them if this program mimicked that.
