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
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
