An anonymous reader writes: Diaspora has launched today, though you could join community-supported Diaspora* pods for awhile already. From the article: "Diaspora* sports some Google+ elements, such as the black bar at the top and a stream on the left-hand side with "Aspects" rather than Circles. Unlike other social networks, Diaspora* encourages people to follow hashtags rather than users, though it is possible to search for people. Similar to Google+ and Facebook, you can post publicly or with a select group of people and add your own "Aspects." ... When you join Diaspora*, you are asked to follow tags. In your first post, including #newhere lets others in the Diaspora* community know to give you a warm welcome. Tags include #music with 6K+ followers, #newhere with 1K+ followers and #occupy with 400+ followers, but there is currently no way to see the most popular tags."
