What is community?
Community- this is such a broad yet narrow term. At its most basic level community is a group of people that communicate on a regular basis. The people in this community must share a common goal or interest. In a community there must be an exchange of some sort between its members. In a community it is not necessary for all ties to be strong ties, but a community cannot be made up of all weak ties, I believe that a mixture of types of ties are what make a community work. Trust in one another is required for community to exist.
Can a community be strictly online?
I am still not entirely sure how I feel about this. I think that if a community can exist purely online, the members must work harder than members in a physical community. There are cases in which the communication between two members of a community can be smiling as you walk down the street. This frequent and simple form of interaction can be what makes two people a part of oneanothers community. This cannot happen in a virtual community; therefore it is important to make conscious effort to communicate with members frequently through whatever means is customary for your chosen community. I think that purely online communities are possible if there is a high mutual interest and frequent communication. It is also important to take more time to build trust and, therefore, create a community in a virtual world.
Is web 2.0 fixing or furthering the problem?
Easily stated both. It is according to the extent to which the user relies on the Internet for communication. There is a point to which online communication may take over, and while you can have meaningful relationships online, it is important to have relationships in the physical world as well. In terms of online communities, such as Facebook, where online relationships are usually extensions of physical relationships, an online means of communication is very useful. Online communication gives people an alternative to the telephone. Now friends in different geographic locations can communicate easily. Facebook also allows users to invite multiple people to an event, allows for a medium in which to share with one another and others, and reminds you of when your friends are having a birthday. Other types of online communities can be just as helpful to relationships, as long as the user knows how to use them appropriately.
