Even when our son was deployed to Baghdad in 2008, we didn't have Skype, so we love it now. We did talk on the phone at least every couple of weeks, so it wasn't so bad.
I think a lot about families who had loved ones in the Pacific theatre in WWII and would go months without hearing from them, or even knowing where they were.
Technology helps out with the anxiety a lot. However, it also lets you know faster when there's danger, and that's not always a good thing. Sigh.....
It's good and bad. Good that you can keep in contact with loved ones. Bad in the sense that it keeps soldiers always thinking about problems back home and is a daily reminder to those back home about what they miss. Also, there are plenty of "helicopter" parents,spouses,girlfriends that now freak out if they don't talk to their soldier daily on skype/Facebook/the phone.
