Flash or not to flash? That is the question.
Disadvantages of an all Flash site:
Maybe I am wrong, you can love flash if the time is right, for instance:
If you don't need to be found in search engines and everyone in your target audience has a fast internet connection, a Flash site may be right for you. If production value takes precedence over budget, a Flash site may be right for you. If you want a 100% Flash site, it will invariably cost a lot of money, and be very beautiful. Oh, and it can take a lot longer to build with flash than other website platforms.
Our personal take on Flash is shared by others:
If you aren't sure what that means, "Flash" is sophisticated software that graphic artists use to create animations and video. Some companies create entire web sites using Flash instead of HTML. The results can be stunning, but there are some serious trade-offs. Don't take this the wrong way. We love Macromedia Flash and the things it can do. We have used Flash within sites and we have done PHP and MySQL back-end programming for Flash sites. We evaluate the features in each new version of Flash and our opinion might change one day. Right now, the best solution is to use Flash within a standards compliant HTML or XHTML site.
