Communities are what individuals envision them to be. This means that there are multiple different perceptions of communities. It is an entirely subjective concept. The best that most of the UK can be described as is a multicultural society. This brings up the image of an all-encompassing single society, or community, which would suggest that no, we don't. However, there are always minority groups or those who don't fit in with others.
It is my belief that while society exists, it isn't a tangible concept. Society is what the individual chooses to perceive it as, which brings up multiple conflicting images. Or, you can ignore the concept, and claim there to be no communities, though the very fact that human beings are social but this to doubt for me.
Talk to neighbours sometimes, but overall community spirit, while still exists in some form, is never going to go back to how it was over 50 years ago. The "Social Revolution", selfishness, the main goal of people all being wealth now and the fact theres no real broad uniting national spirit now, just loads of diffrent "diverse" groups instead has all led to the way society is now.
I think the addition of the internet and also the addition of things like: BBM, MSN, Onine forums, and social networking sites allow us to engage in a more social manner, but this social manner is not probably what everybody else here is thinking (IE: going to somebody's house and talking to them or bumping into somebody on the street). What i am trying to say is that the way we communicate mainly nowadays is usually by some kind of online messenger service, i hate to say it, but i use the internet for conversational purposes etc more than i probably actually speak in real life. Whether this kind of communication is good for us or not as humans, is whole other discussion.
The point being that saying we don't really talk to each other or meet up and socialise together is true, but it is also countered by the fact that we socialise and converse in different forms that are relevant to the times that we reside in.
On the ideas of community, it is true that we have drawn apart, mainly due to the internet and independancy. But once again the internet creates communities of its own, for example: This forum we are talking on right now is a community, online console games have communities, hell even social networking sites could be considered communities.
It is sad looking on the outlook of our society and where we socialise is so confined, esepcially so that it is so confined to the internet, and/or confined to institutions that are either compulsary to ones self, or just through fate itself.
