Author and media theorist Douglas Rushkoff has quit Facebook, but for a reason that goes beyond the usual concern with Facebook’s privacy problems. He says: “Through a new variation of the Sponsored Stories feature called Related Posts, users who ‘like’ something can be unwittingly associated with pretty much anything an advertiser pays for. Like email spam with a spoofed identity, the Related Post shows up in a newsfeed right under the user’s name and picture. If you like me, you can be shown implicitly recommending me or something I like — something you’ve never heard of — to others without your consent.” We find that exceedingly troubling, since it means that you lose even more control over your online persona on Facebook. follow link
Type an em-dash on an iPhone
Typography and punctuation geeks rejoice! It's easy to type an em-dash on the iPhone's or iPod touch's virtual keyboard. To do so, tap the .?123 key to switch to the numeric keypad. Then touch and hold on the Hyphen key to reveal a pop-up strip showing an em-dash. Slide to the em-dash and release your finger.
Note that this basic trick works with many other keys on the virtual keyboard.
