For those who arrived here looking for Fred Clark's posts we can do no better than to quote his earlier announcement:
Slacktivist is moving, heading over to join the growing community at Patheos.com.
The new URL will be: www.patheos.com/community/slacktivist/.
Those of us who are working on adapting this site for those who don't feel comfortable at Patheos wish to express our continued support and respect for Fred. We're in communication with him, we're asking questions about what works for him, and he's being very gracious and helpful. Likewise, the people who don't feel comfortable at Patheos are, for the most part, uncomfortable with Patheos but still hold Fred in high regard, and his e-mails have expressed concern and sympathy for them.
We are trying to work out the best way of dealing with changed circumstances with mutual respect and good will. Once we get things up and running, our aim is for the two sites to be places where friends can visit friends easily.
