Earlier this year, I decided to make a group on the site Diigo for our whole Social Technologies class, to collect together all the useful links, articles and pieces of research in one place where everyone could easily access them. Diigo is a bookmarking website, designed so that you can find your bookmarked websites on whatever computer you are logged into (Diigo also has a nice iPhone/iPad app which I started using, though sadly it’s a stripped down version and you can’t use it to look at groups, hopefully that will get implemented soon) but the groups function does much more than that. It works a lot like a blog in that it has a tag cloud, and ways to search for tags.
But the best part is that you can comment on other people’s links and start discussions about it. You can also use the group like a forum, to post a comment or topic thread.
However, since we were a small class, and the Diigo group has not been up for very long, there isn’t a huge amount of this going on. Nonetheless, I believe that we have created a useful library for Social Media and Online Culture Research here.
