I believe this post is spam of some sort. The same person has posted only one question on many forums in the last several weeks. Sites representing everything from astronomy to light boxes to computers to aikido to david allen. They all say something inane like "What's GDT?" Gets people worked up answering him, but never posts again. Probably racking up google hits for some reason. For example, donationcoder pops up first when you search for the poster (whose name shall not be used by me), then a long, long string of other links.
