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

Does anybody know a site called YouTube? It wouldn't exist without flash. Flash has great video/multimedia capabilities that simply cannot be ignored.

Flash is amazing when used in the proper way, in appropriate circumstances and when the designer/coder has taken care to embed basic accessibility features.

The thing is, like all good things, there's a lot of abusive use (flashturbation). Especially in the beginning, when people just want to slap Flash wherever they can just to show off.

But I strongly disagree that Flash sites are bad: When made properly, and with good UI design and accessibility, they bring a whole new dimension to the web.
