Another concern has cropped up with Facebook, highlighted by Nick Bilton of the New York Times. For people looking to spread the word on Facebook, traffic in the form of “likes” and resharing would seem no longer to be organic, but must instead be greased with a little green. That’s mostly a problem for those doing some sort of business promotion on Facebook, but should give anyone considering Facebook as part of a marketing strategy significant pause. For what it’s worth, we see almost no traffic from our Facebook page. follow link
Cull Graphics Quickly with Preview
You're faced with a folder full of images, and you need to sort through them, trashing some number and keeping the rest. For a quick way to do that, select them all, and open them in Preview (in Leopard, at least). You'll get a single window with each graphic as an item in the drawer. Use the arrow keys to move from image to image, and when you see one you want to trash, press Command-Delete to move it from its source folder to the Finder's Trash. (Delete by itself just removes the picture from Preview's drawer.)
