Myth #18: Flash is evil

In the earlier years of the internet, many web designers preferred overusing Flash animations, ignoring users with slow internet connections or without Flash player. These early implementations often neglected basic usability principles, too, therefore the whole technology was criticized for being unusable and inaccessible.

All that said, you should still consider the limitations of Flash:

  • Flash should only be used when it adds value to your visitors’ experience over the standard browser functionality.

An interactive Flash product presentation can also be a very effective sales tool while an e-commerce site totally done in Flash is not recommended at all.
  • Although almost every desktop internet user has Flash installed, many also use Flash blockers.
  • Most mobile phones, including the iPhone and the iPad, don’t support Flash, your Flash-only content might be inaccessible for a growing number of mobile device users.
  • To make your Flash site accessible to everyone, a non-Flash version should be available, too, which will need extra resources to develop.
  • Several security experts, such as Symantec and McAfee, recommend users to disable Flash when visiting unknown and untrusted sites because of its vulnerabilities.
