I use WA all the time, all my friends are on it plus I have certain groups of chums, family one etc.
I love the face time /video, my DD and DS both just call me on that, My DS lives about 1.30 hrs aways, so it lovely to see his small daughters, they show us what they have been doing that day.
I also speak to my neice in Australia and see what's she up to in her garden and touch base with her. Plus my chum who lives in France contacts me when she cooking in her kitchen, while she's waiting for things to cook.
So much more than a phone call.
