This is timely considering google's announcement to dump indexing of flash (swf) assets. I get it, the format is unused, buggy, and possibly insecure. That said, much of the nascent internet was built on that. Even "All Your Base" was originally in flash.
On the plus side, a lot of the non-interactive Flash content is now on YouTube. I was going through old Weebls Stuff animations the other day, it was a real blast from the past.
