Digg this, Tag that!
Have you ever dugg an article, blog or profile before? Digg is a social networking site that allows users (you, me and everyone we know) to submit and "digg" a story - vote on it's popularity or bury it based on a yay/nay, like/dislike attitude. If a story gets enough diggs it get promoted to the front page showing the number of diggs (votes) next to the title. Stories can also be posted to a user's blog as soon as they digg it. If you blog or write stories online (for your library or for personal enjoyment or necessity) posting your story to Digg will help give your site and writing more exposure and bring more traffic to your site.
Why do I care? You may ask. Well, as one librarian, the Connecting Librarian states,
For [stories] to get a lot of diggs, either the people posting the stories have to know a lot of people who they encourage to digg their entry, or it is an entry of great interest to a wide variety of people. Either way, its something that's of interest to a lot of people and therefore I think that I, as a public librarian, should be aware of.
Digg is not the only site out there that does this kind of thing. Another site that works on the same concept, stumbleupon actually has more registered users than (the popular) Digg. However, stumbleupon not only uses categories (mediated source) to separate and organize stories, like Digg, they also use tags (social networking) to organize stories. This form of filtering actually gives stumbleupon a leg up on Digg as far as user contributed content control.
Again, you may say, what do I care? You should, because as librarians, as organizers of content, we need to be looking at how users of the world wide web are not only categorizing and organizing content on the web, but also, how they perceive the information - important/not important. That's what these types of user-driven social content ranking sites are doing. They are letting us know what information people deem important and popular. Our role as filter for finding/suggesting best sources comes into play here as well as a good scrutinizing eye.
btw, if you would like more info about these sites and others like them, TechCrunch has a good article with summaries of major players.
