Back in 2006, I posted about the Promise of Web 2.0 - Comparison to Macros, IDEs, and Visual Basic and pointed out that Visual Basic was a huge innovation that allowed many new developers to build applications.
We've been using Google Apps as the basis for developing some very interesting online applications. The announcement today Building UI in Apps Script just got a whole lot easier that shows how you can use a drag and drop - Visual Basic like. It's very crude, but interesting to see.
This is a long way from what you can do with Microsoft Office, Scripting, Visual Basic. However, because of the cloud nature, this is interesting to see. That said, it could very well be that Microsoft is able to beat Google to this.
