Google Apps users and those looking for a central, convenient spot for their contacts, take note: Google's stand-alone contacts site now lets anyone with a Google account add and manage names and details.
Anyone with a Google account, or those who sign up for one, can head to google.com/contacts to start adding and managing contacts. Why, you might ask, would a non-Gmail user want to do such a thing? For one, Google's Contacts manager supports imports and exports from a wide range of apps, like Outlook, Yahoo, Hotmail, and, using the free A to G app, Apple Mail. So it makes for a nicely web-accessible backup, and won't require another account if you're already using another Google service.
Google Contacts is free to use with a Google account; Google Apps users have to get their administrator to enable Contacts from their "Add more services" link at the Control Panel.
