Let's face it. Any good Web 2.0 strategy (or web 3.0) needs to have a "dynamic language" story to attract serious web developers. Languages such as Ruby, Python, PHP, and Perl are seeing tremendous gains in adoption by Web Developers.
No two organizations are alike when it comes to customizing their online presence and Internet Marketing campaigns, and these dynamically typed languages are increasingly becoming the language of choice as API extensions (see Google App Engine's use of Python).
Now that Dialogue Script is generally available and actively used in production, we've started turning our attention towards how to provide Developers with more programmatic control over the display and processing of web forms and portal applications, similar to how Salesforce employs Apex Controllers in Visual Force.
Our open source C# and ASP.NET API is an extremely powerful option for those familiar with Visual Studio.NET and managing strongly typed, compiled languages. But we wanted to evolve our platform and embrace the latest trend in dynamically typed languages and to go one step further by keeping the entire web development experience service-based (ie through a web browser or rich client).
Fortunately, the Dynamic Language Runtime (DLR) will be made available to us very soon and i-Dialogue Developers will have their choice of several dynamic languages to choose from when embedding rich programming logic into their web forms.
The DLR will give Developers the "glue" necessary to mash-up Google, Salesforce, Microsoft Live, Fedex, and any other web service using a familiar programming environment. The feedback from making changes will be instantaneous (no recompiling, moving files, or unit tests), making programming an instantly gratifying experience.
The DLR extensions to Dialogue Script will drive the innovation of new development process lifecycles and quality control processes that enable globally distributed teams to iteratively and incrementally evolve complex websites, portals, and campaigns using nothing more than a $599 laptop and browser.
The entire i-Dialogue object model will be made available, so DLR scripts can programmatically control all facets of a well rounded Internet Marketing Suite, including Profiles, Pages, Email, and Web Forms.
If you've ever written a VB macro to customize an Excel spreadsheet or Word, then you'll feel right at home with this new extension. This is probably #3 in the priority queue right now, with a couple tremendous new features taking priority right now for delivery by Dreamforce, so I'll keep you posted on it's evolution.
Suffice to say, we'll seek to leverage the DLR out of the box as much as possible with very few proprietary additions, so any O'Reilly book or MSDN article on the topic will be 99% applicable, if you want to get a head start.
