A great list from Ian Lurie's "Conversation Marketing": The Internet Marketing List: 59 Things You Should Be Doing But Probably Aren't. My favorite item on Lurie's list is right there at the top:
1. If you have a Flash introduction on your web site, delete it. If you don’t agree, try this: Shove your head into a bucket of water. Stay in there, not breathing, for 10 seconds longer than is comfortable. That’s what you’re doing to your customers. Delete it, please.Yes, Flash intros look cool. But just because you can do something cool, it doesn't mean you should. Remember, if it doesn't advance the conversation with your customers, get rid of it. Unless you're in the Flash animation development business, all a Flash intro does is get in the way.
And if you need more ammunition to make a case against Flash, here it is.
