I just finished up a post on HTML 5 and Flash for InfoQ.com. The news post just covers the conversation happening in the community(s) (not my opinion). I am glad browser standards are finally evolving, and think all developers will benefit from the advancements. Being a Flex developer, I have obviously embraced the idea that third-party plug-ins are not a bad thing when trying to build real applications. It is too early on a Sunday morning to get to far into this debate, but I wanted to throw out a couple of points:

1. Since the language around browser standards is very feel good, with terms like “open web,” I think it is often lost how much big companies, such as Google and Mozilla, stand to gain if developers validate their assertions around browser standards. In all reality, the open web vendors are no different than the vendors providing “third party runtimes,” they want / need people to use their platforms.
2. The “open web” never existed. Let’s take a look at a quote from Ian Hickson, HTML 5 specification co-editor and Google employee:
   

   “It would be a terrible step backward if humanity’s major development platform [the Web] was controlled by a single vendor the way that previous platforms such as Windows have been.”

   Not only does the language seem a bit dramatic to me, but I think there is little risk of this happening (outside of the standards). Historically browser standards have been the main catalyst in bringing us down to the lowest common denominator in web development. We have all worked on projects where the management decided to just build the application to work in IE because the browser standards are unreliably implemented across browsers.

The reality is that the RIA space is currently experiencing wonderful competition across vendors (Flash, Silverlight, JavaFX) with applications being built and deployed on a number of different platforms. Frankly, none of the current platform advancements that are making developers lives easier have come from standards based implementations.
