If you're referring to GPLJonas' comment as containing "perfect grammar, good use of white, buzz words and directness" then I'll take that as a compliment! Everything but the first three and last paragraphs were copied from my blog post! (http://blog.fosketts.net/2012/01/03/microsoft-adds-data-deduplication-ntfs-windows-8/)
FWIW, I'm not a Microsoft shill or astroturfer. I'm a blogger who happened to write about MS' dedupe yesterday and it got quoted here. I only noticed this thread thanks to all the Slashdotters coming over to have a read. Hi!
Indeed, I'd love to see Linux implement deduplication similar to Microsoft's new NTFS tech. But of course, it's a major development effort and LOTS of patents are involved.
