Yes we do use flash as and when required. It is important to note that there are times when flash animations can be an asset but it would be unwise to use “flash” to create an entire website or even entire pages of your website as search engines are not able to read the content of flash and therefore any words used in animations will not be indexed by the search engines.
Generally it is best to use flash for smaller banners, advertisements or demonstrations and incorporate the flash animation into a web page which also includes some written text in html. This way the search engines will be able to index your information
