What is so evil about a Flash based website?

Question

I have the feeling that Flash-based ( or Silverlight-based) websites are generally frowned upon, except when you are creating games or multimedia-content rich applications.

Answer 1

Flash adds another heavyweight component that's required to properly view a web page. The flash plugins are often buggy and can crash a browser. Flash pages often are used to make cutesy animations and other things that make it harder to quickly navigate a site.
