Five years ago, Steve Jobs lambasted Flash and detailed why Apple abandoned it. At the time, he was an outlier. However, now people are starting to see why Jobs felt the way he did. It's all about the user experience. There's a valuable lesson to learn from the demise of Flash: if what you're doing isn't creating great user experiences, it's creating problems.
Worse yet, those problems and poor experiences are going to drive away customers and prospects. Here's what you do: first, get rid of Flash if you're using it. There are better alternatives out there (e.g., HTML5) for creating interactive experiences for your online visitors. Second, create valuable user experiences! Otherwise, your prospects and customers will be gone … in a flash!
