flickr has groups and pools and creates a community of practice. Twitter reinforces personal relationships.
My twitter stream connects me to people I know, and, as I wrote in the previous entry, helps us stay abreast of each other's goings on in meatspace and online, no matter what service or host we are using to publish content.
Flickr, with is proliferation of group discussion, photo pools, cross user tag search is a great resource for someone interested in learning and practicing photography. It is easy to connect to or start a community of practice.
If I post a new picture and send out notification via twitter, that picture gets seen by my twitter crowd. These are almost entirely people I know in the real world or at least have some more general personal connection to, not a connection defined exclusively by a shared interest in photography.
If I post a new picture to flickr and add it a relevant photo pool, I get views from users from across the world, views from people that have some similar taste or interest. If I am lucky I get a comment from one or two of them. This works both ways. I can find photos and discussion that are of interest to me. Right now, all this activity is happening in a centralized service.
Is there a way to get to make these connections and foster this community in a distributed way. I want to start posting my pictures on this site, where I can own and exert control over them. I still want to take part in the community at flickr. I don't want to double post pictures. I guess we can't have it all, right?
