I'm really sad to see that they totally blew it.

The performance of a webapp with the accessibility of a desktop app. Not to mention that it's closed source. This is a tremendous step backwards.

Looking at the implementation of the open sourced packages is discouraging as well. It looks like they are using a Backbone inspired jQuery infested nightmare of clientside MVC.

Maybe my bitterness comes from the fact that I've already been down that road and it leads to a bad place.

Here's an editor that has deep Github integration, runs in the browser, and self hosts: http://www.danielx.net/editor

Maybe I just live too far in the future.
