Porn comes in all shapes, sizes, colors and formats, just as about everything else on the internet. You're bound to be able to find most things on the internet not requiring flash, but many other sites do too. Flash enabled rich internet applications first, and was there to enable such functionality before our browsers could natively handle such things. Flash is an extension of the browser, an extension featuring functionality heralded now by HTML 5.<p>I don't get why people hate Flash. Sure it's proprietary, but it was there first, doing something we all wanted before anyone else came around. And frankly it's still serving that purpose because HTML 5 still isn't ubiquitous enough.<p>It probably contributed to YouTube's success, and the general flourishing of online video. It's enabled rich browser based games. I think it contributes greatly to the advancement of the internet, if not by any other means than by encouraging the proliferation of rich applications.
