I've played with LiveCode and have to admit that it still seems a lot more complex than HC/SC. Maybe I'm biased or nostalgic because HC had a really profound influence on how I develop software. I was ready to give up on programming the Apple Mac (possibly on programming altogether, and I thought that I was a good programmer) when along came HC.

The challenge for LiveCode is that in the intervening years, of course the complexity of the system has gone through the roof. I think HC represented a conscious choice to limit its own feature set in order to make it presentable to novices, which opened it up to criticism from commercial programmers who thought it was a toy.

I honestly don't know how to create a tool that satisfies the pro's without blowing away beginners and hobbyists. Possibly the magic of Python is that the basic package simply doesn't come with any advanced features (they are installed as packages), allowing for an uncluttered learning environment.

Oh, I didn't know that they went open source. That's cool.
