Hm. I probably shouldn't say this, since I am hoping to take advantage of it, but I am curious how you would stay relevant if a completely open source platform build around drag-and-drop Polymer/web components managed to become popular? Or even any kind of open source composable widget-based platform.

Or maybe that just isn't a concern because so far nothing like that exists?

I like the idea of Weebly, I think building web software should be based on components for the programmers and usability for users. But I don't see how a closed platform stays relevant.

I think its just that most web developers still don't understand widgets.
