*sigh*
Flash is pretty, Flash has decent compression, but Flash is completely unneccessary. I've done mapped-GIF pages that are as fancy as any Flash page, and will do so again. It has some nice functions, but claiming it's the end-all format for all things internet reflects a lack of understanding of things not Flash. It's convienient, nothing more, nothing less.
That said, convienience is important online, of course. That wasn't a criticism of Flash so much as a summary of its functionality. The only problem I have with Flash is the excessive reliance some people put on it- the Zuxxez mainpage being an example. There's such a thing as too much Flash, and it seems a growing number of people don't cross that line so much as book a flight for six billion miles beyond it.
Also, lots of people don't include non-Flash alt pages anymore, which pisses me off.
