From the NY Observer:
exerpt --
Mr. Rather’s report hadn’t been over 10 minutes when a post appeared on the right-wing Web site FreeRepublic.com from "TankerKC," saying the documents were "not in the style that we used when I came into the USAF … can we get a copy of those memos?"
Three hours and a little later, fat met fire with another FreeRepublic posting, this one from a blogger named "Buckhead." He (or she—Buckhead won’t reveal his identity outside cyberspace) wrote:
Every single one of these memos to file is in a proportionally spaced font, probably Palatino or Times New Roman. In 1972 people used typewriters for this sort of thing, and typewriters used monospaced fonts. The use of proportionally spaced fonts did not come into common use for office memos until the introduction of laser printers, word processing software, and personal computers. They were not widespread until the mid to late 90’s. Before then, you needed typesetting equipment, and that wasn’t used for personal memos to file. Even the Wang systems that were dominant in the mid 80’s used monospaced fonts. I am saying these documents are forgeries, run through a copier for 15 generations to make them look old …. This should be pursued aggressively.Here the plot starts a-thickening.
First (leaving aside how suspiciously well Buckhead puts sentences together for a righty blogger), there’s the extraordinary, yeah, boggling, knowledge of typewriting arcana. More remarkable still are the circumstances under which discernment occurred. Namely, viewing the document on a TV screen from a presumed distance of six to a dozen feet. Folks who make their living at this sort of thing rely on magnifying glasses, if not microscopes. And they don’t venture opinions unless the document’s in their puss.
