Definitely, my web cam and SKYPE are busy on the weekends, when I can take a pick at most of my family in Poland. All for free.
I used to pay AT&T 0.99 cents a minute to call Poland, or write a long letter.
If I need to call now, it cost me 0.049 cents only, so we can talk until I'm blue in the face :)
