I think flash is great for smaller sites but when things get big flash takes too long to load. For example, a rock band website, great has all the tools you need loads in a reasonable time and looks much better than a standard web site. But for something like argos or a big shopping website it would take such a long time to load.

I think flash is the future of all personal sites and smaller sites but it just hasn't got what it takes to power big sites.
