A lot.
Really hates sites that offer no HTML alternative and no "skip flash" link.

So. Keeping that in mind, you can begin playing with the tutorials and maybe insert small objects on an expiramental basis. DO NOT fall into the flash navigation trap, and don't put any site content inside your Flash, search engines don't follow internal Flash links or read the content.
Begin by downloading or buying MX and going through the tutorials, that's where you start. :D
