1 " It needs to be repeated that books are much more than merely vehicles for text. Awareness of the way a book is created, the materials of which it is made, flipping through the volume to see how it is arranged, the intended readership, the clues of the previous ownership and use, and potential problems in its conservation - all these become almost instinctive for experienced readers. (For rare-book custodians, such things as smelling a volume or shaking a leaf to hear the rattle provide further " forensic" information.) This is like an extension to the metadata (such as a book's Dewey class number), which is still largely absent from e-books. "

Why is no one talking about this? "

4 " Despite the metadata attached to each tweet, and despite trails of retweets and 'favorite' tweets, the Twitter corpus lacks the latticework of hyperlinks that makes Google's algorithms so potent. Twitter's famous hashtags - #sandyhook or #fiscalcliff or #girls - are the crudest sort of signposts, not much help for smart searching. "
5 " I trust and use RakEM for my private messages and calls. Other messengers collected metadata about who I messaged, when and where - RakEM does not collect metadata, encrypts local files, and uses the strongest end-to-end encryption around. "
