The difference looks quite impressive!
If I may say... posting your essay on APUG rather than Facebook might be a wiser investment in the "analog" future. On facebook it's, for all intents and purpsoses, private, whereas APUG is viewable by anyone and search engines will find it.
Then again, maybe you'd prefer it that way. But I for one encourage you to consider posting the essay here, or maybe even in the articles section. It certainly seems like an important contribution to the art..
