This is nothing more or less than a test. I want to make sure I can publish to this Blog using Performancing's editor within Firefox.
Part of what I do is experiment with new technologies so you don't have to.
In the case of Performancing, it works as advertised -- a Blog editor that resides inside my Firefox browser -- but then I don't yet know why you or I would need it. Of course, that's the issue with many new technologies, isn't it?
