Spock has become a great resource for finding people. I find it so useful I actually created a Plug-in for the Mac OS X Address Book. With this plug-in I can click on a person's email address label and choose an option from the context menu to lookup the email address on Spock.

Let me know if you find it useful.
The Christmas and New Year period is a time to reach out to family and friends. To help me do this I turned to Shape Services and their IM+ web service for iPhone and Skype users - s4iphone.com . This neat web application allows you to log in to Skype and using SkypeOut place calls to any phone number. This is great for making inexpensive international calls. The service works by prompting you for a number at which to call you. The service then places two outbound calls. One to whoever you want to call and the other back to the phone number you nominated. This could be your cellphone or a landline phone you have access to. The two calls are then connected. This is a cool service. You can pay $4.95 per month to use the service or buy a perpetual license for $25.00. You also need to buy SkypeOut credits from the Skype Store USA. This is a really useful service and well worth checking out if you have an iPhone.
The IM+ Service is set to become even easier to use with the rumor that the next release of firmware for the iPhone will allow sites to be bookmarked and added to the main menu screen. GearLive has the scoop in a video showing off some of the features coming in the forthcoming firmware release. We can expect to see the firmware launched around MacWorld.
