Just to add a note to this... Self does not have any working GUI/app framework that would be sufficient for creating an usable application. And as I see it, Self will not have it in near future. What Self has, is a great computational mechanism and different view on how to "model a problem". Ant there is the power of Self. Yecel named it "scripting", others can name it "integration" - with that both sides can gain. Application developers will get powerful computational engine and Self will finally get users (developers, testers, ...).

The advantage of Self is not only "scripting". I think of scripts as of some small pieces of code for automation or customisation. The advantage is, as I have mentioned before, the different computational model and well tested, fast runtime. Those are features that no other (or very few) scripting languages/environments offer. This moves Self to another, higher level, where one can use it not only for small pieces of code. One can use it for larger (user customisable) parts of an application. There are lots problems that can be solved in Self much more easier than in C/C++/ObjectiveC.

How I see it? Application using one or more Self environments. Ok, now I let my imagination go... What about stadard application as a frontend to a distributed self environments on different machines? It's just an example, but you get the idea where it should go...

I am not a Self developer, I come from another world and I am just saying how I see it from the outside. I think that a fight for a user environment is lost at this time, what can be won is a battle for exceptional computational environment/engine.
