How regularly do you chat to ALL your friends? I'm sure you must have hundreds like most people. You undoubtedly have some that live abroad too?
Isn't it just wonderful to be able to keep in touch with them 24/7 without having to speak to them all individually - but still have the option to ring a friend if he/she wants a private call?
Also, isn't it much easier to share pictures of a night out with everyone involved in one central place?
I don't know why people are so anti facebook. I must admit I find all the apps etc. annoying but since all of my friends are in their mid to late 20s and 30s and 40s that doesn't seem to be too much of an issue!
For me it's brought me back in touch with old friends, helped me keep in touch with family and friends around the world - and means if I don't have the time to write several dozen emails to different people I can get everybody together in one point of contact area.
I think it's really a rather useful tool.
