Two main things for us to consider when going on a web project

Even when using Flash now, there are users who do not have Flash installed and thus, unable to view the website and some, not motivated enough to download the latest version of Flash decides not to view your website after all.
HTML 5 requires compatibility of the newer browsers to support its features. You might be surprised but many browsers are still on the old version of IE that comes shipped together with the computers that came together some 10 years back (or maybe 5).
