This was a conversation I had with our webmistress shortly after taking my current job. I was put in charge of designing my departments intranet site and did an interactive org chart with everybody's contact information.
Webmistress: We don't allow flash on our websites. It is unprofessional to use and is nothing but "wiz-bang eyecandy"
me: I'm sorry for them, but I will be using Dreamweaver, but back to the org chart, why can't it be more engaging than a static image?
Webmistress: Well, when I roll over this persons photo, their contact information appears... if the user rapidly moves the mouse on and off the photos, it could create a blinking effect that could send them into a seizure.
me: ... shoot me now
