Gosh. I hate when I can't put things on a roundto pile.
Whatever you choose to do about your Flash content, do something. Obsolescence, in this case, doesn’t just mean that Adobe is going to stop supporting the software and allow it to age out – it’s going to become blocked. Websites will simply refuse to load pages that have Flash content on them, and every time a new version of a browser is released, it will become one step further away from supporting Flash. The clock is ticking rapidly, and the end is coming. Flash has had an incredible run, but it’s reached the finish line, and it’s time for it to enjoy a well-earned retirement. We cannot stress these points enough!
