Last night delicous.com was in my dream, which, while decidedly odd, got me thinking about some things. I’ve been focused mainly on the moment of learning that comes when a site is tagged, but while looking at my delicious tags, I noticed that they are also all connected to each other by their shared tags. For example, I tagged two sites as “web2.0″. One was the Institute for the Future of the Book, and the other was LinkedIn.com, a social job networking site. Both are rightly tagged as web2.0, and yet, we tend to focus the definition of web2.0 as that thing which it is related to in the tag, rather than the whole definition. In other words, when I see the Insititute for the Future of the Book, and its tag, web2.0, I think about how web2.0 and If:book are related. I don’t think about social networking and web2.0 until I look at LinkedIn.com, but both are part of the total definition of web2.0. By looking at the tags as a whole, rather than just an individual site and its tags, we learn more about not only the site we tagged, but also the meaning of the tag itself.
