God... what? First off, which Pascal textbook would be both old enough to include a floppy disk, yet new enough to include a Twitter clone? I simply don't understand his main argument. App.net will be unsuccessful because it's just a clone of Twitter and people won't support a Twitter clone? App.net is certainly not and will not be a Twitter clone, and anyone who has spent more than five minutes looking at the platform, its roadmap, its API docs, etc., would know that.
