Query: In what ways can online "selves" transgress the limits of physical selves in terms of community building?
I think that online selves can form stronger ties in terms of activism than physical selves sometimes. People are more likely to share online and more likely to be honest. It gives a safe space for people to reach out and learn other people's stories, while at the same time allowing for people to build communities, alliances, networks, and foster activism.
The digital self has more freedom in this type of arena and is more likely reaching out and interracting with people in similar positions. Blogging identity demonstrates individualism and the freedom of expression. I think that online selves are necessary to connecting with people with similar interests. Years ago when online media didn't exist, it was harder to assemble or come together under a common belief without seeking it out or showing interest in it initially. Online media allows access to sets of knowledge beliefs one probably wouldn't have attained otherwise, or even stumbled across. The aspect of "stumbling across" can foster connections and interest in things one didn't know about or find important before. It let's people in marginalized groups know that there are people out there just like them, it reasserts normalness and creates communities that wouldn't have come together otherwise. In this aspect, our online selves have more access to communities than our physical selves.
