Learn more about social software

About Five Weeks to a Social Library "is the first free, grassroots, completely online course devoted to teaching librarians about social software and how to use it in their libraries." Though the course was run back in February all the course content is freely available via screencasts, webcasts, podcasts and links to readings, among other things. The course covers Blogs, RSS, Wikis, Social Networking Software and SecondLife, Flickr, Social Bookmarking Software and Selling Social Software @ Your Library. This site looks well worth exploring.
