| The Daily Kos community is so huge, with more than a hundred thousand active users and hundreds of diaries posted every day, that many communities have formed within it. In those groups, diarists and commenters can get to know each other over time.
The "Edwards Evening News Roundup" was that kind of community for most of 2007. People came looking for those diaries so they could catch up on the news of the day and with other Edwards supporters they had "gotten to know" online. After John Edwards dropped out of the race, many of the active diarists in this group formed the EENR blog, which is now Progressive Blue.
Daily Kos has generated other communities that have nothing to do with politics. Frankenoid posts a Saturday morning garden thread every weekend, for instance.
On Monday nights a group of people take turns writing diaries about bereavement in "The Grieving Room" series. If you have ever experienced this kind of loss, I recommend that you read these posts.
Last night's edition by Papachach, a widower with three young children, was quite moving.
On a related note, if you or anyone you care about has experienced depression for whatever reason, I recommend reading this piece, which made the top of the Daily Kos recommended list yesterday: I hope this message reaches the right person.
UPDATE: On the subject of bereavement, I recommend reading this interview with Elizabeth Edwards from last year, in which she shares how the sudden death of her son Wade changed her life and her faith.
