We can talk all day about, can you use it, should you use it, what is it. The bottom line that we are really talking about is increased revenue for company money expended. There isn't much money to be made for a company when a major form of there public perception and information distribution is so goofy. Books and magazines look and behave the same everywhere. Radio sounds the same on all radios.
TV looks the same on all televisions.
The web was our first chance to do better than that, and we're blowing it. Automakers are putting browsers in cars. Web access is showing up in phones and PDA's. The essence of the web is the ability of the end user to get content on any device at any time. Flash can be a powerful tool for poor design.
