It's funny how some people separate FB from being real Just because you talk to someone on FB doesn't mean you are not a real friend they are not pretend people I think it's only very young people that have hundreds of (unknown) friends I have about 100 people on FB they are mainly family, friends, or friends that I haven't seen (or likely to see) for years like school friends, then also new friends that I ve met through a variety of means, people I probably wouldn't have the means or time of keeping in touch with if it wasn't for FB ........
The difference from GN is the huge variety of local groups to get involved with, I belong to a number of buying/selling groups no fees no postage to pay A local photographic group, a local history group, a community rubbish picking group etc the other difference is the huge sharing of photographs which I find fascinating I don't mean someone's holiday pics but the amount of things I ve learnt and seen are eye opening
I don't use FB as an alternative to real life but an extension
Lastly it's a wonderful form of using wifi for communication I click on my son's FB profile in NZ and his voice answers and we have a 'free' chat or if I click on the video symbol we can see each other The same with my young friend in Zimbabwe we would never have seen or personally spoken to each other (far too expensive) without FB
I don't see it as a alternative to GN they both have a place and I enjoy both
