What makes a community and does tech provide?

I feel like a community is where one feels welcomed, part of wholeness, togetherness and friendship. Also a community can be a lot of people or just a few and people who share the same ideas or bring new ideas to the table.

I would say yes tech does provide for the sense of community it is just on-line versus in person. Take Facebook for instants where you can be a part of a group (community) that like the same show/artist/etc. and it gives people a chance to talk with others about it. Also there are some communities on-line that are for people who have lost children and it gives them a place to share their stories and help each other out in a difficult time and gain awareness. 

Also I have heard of people meeting friends on-line and whom they have never met. There is also chat rooms where people go on and chat about either certain topics or a varied of things. So yes tech can provide for a community just as one would think of community in the traditional terms.
