The program of SDoW2008 has just been published on the workshop website. In addition to the 7 full papers, 2 short papers and 2 demos, there will be two keynotes: the first one by Peter Mika on "Semantic Search and the Social Web" and the second one by Harry Halpin entitled "Beyond Walled Gardens: Open Standards for the Social Web". Attending TPAC this week, I can tell that the second one is really a hot-topic: there were some discussions yesterday in the SWIG group meeting, two related lightning talks today, and an upcoming "Workshop on the Future of Social Networking" lead by the W3C Mobile Web Initiative.
The SDoW proceedings were also officially published today on CEUR-WS, volume 405:
http://CEUR-WS.org/Vol-405. If you're attending the workshop, consider reading it before, as it might help Q/A and discussions. There will also be a lightnight talk session, so that any attendee will be able to present his works / ideas regarding Social Web and the Semantic Web.
