Dan Schultz doesn’t like Facebook or Twitter because they are too focussed on individual expression rather than the community.
That may be because he is using them wrong. I liked photography as a kid, but I didn’t know any photographers. Flickr happened to come into my life just after I bought my first digital camera. My participation in photography exploded. Not because I had a way to post my photos but because I had a way to find other local photographers for mutual encouragement. Even better was forming local groups to encourage people to meet. The value of Flickr is developing the community.
Similarly, I got into Twitter because my community, peers at other universities running the same software as myself, were seeking help there. Any place with answers to the problems we face, which is where people with the answers are watching, is where we go. Twitter was the place to get the attention of the right people not a forum like phpBB. (There are already lots of email lists.) My other community, people using the software I run are also on Twitter. I’ve resolved issues for many clients by finding their public complaints and offering solutions. When my focus changed away from using Twitter for the community is when I stopped liking Twitter.
Personally, I have yet to find much sense of community in the phpBB, Google Wave, and Ning. So I find it strange these are the exemplars of community applications. They seem fractured so one finds dozens of groups to covering the same interest. Sometimes this is because some moderator upset a portion of the community with draconian behavior causing people to form an alternative community. Bad blood exists for a while. Other times people set up a new community unaware others exist.
