Your Thoughts - Designs issues (websites)

just thought id strike up a conversation rather than a post ‘how cool is my site’ thread.

As im sure some of you regular members are aware myself and good friend have started creating sites working with the latest craze of CSS and accessibility issues.

i once really wanted to get into flash work and it interests me but i felt that if i comntinued to put myself throught the learning i would also put myself to a disadvantage as the new craze is ‘ease of use’.

DISCUSSION

What do you feel is more important - creating a breathtaking flashsite which lets face it you cant use without a mouse.

OR

creating a user friendly site fo all to enjoy? Accessibility being the main idea?
