For months I've been fascinated with del.icio.us, and the subjects of folksonomies and social software. One thing that impresses me about the service is the potential it holds for doing some really interesting data analysis about how people discover and share information, and the ways social software services can make that process faster and more efficient.
This afternoon I played around with IFTF's del.icio.us account, and gathered a few simple numbers on how "sociable" we are. A few minutes with Excel, and we've got a couple simple graphs-- and I do mean simple.
The first shows how many of the 368 bookmarks in our account are shared by anyone.
More than half our bookmarks aren't shared with any other user. Given our fairly specialized interests, and the fact that we often will bookmark pretty academic or obscure stuff, that's probably not a huge surprise.
If you look just at the shared bookmarks, the pattern becomes a little clearer.
At the far right, there are a few pages that a LOT of people have bookmarked. Not surprisingly, most of these are either blogs, or articles about social software or del.icio.us. At the other end of the graph, you see that nearly three-quarters of the bookmarks that we share with someone are shared with one to five other users.
You can see who else is bookmarking the same things you are, and when they bookmarked those pages. Choosing a few at random, I found that about half were pages that other people had marked first, and the other half were pages that we'd marked first.
There are two things I'd really love to know.
First, in some cases, each user who bookmarked a page found the it through Google, or a link from a news article, etc.-- i.e., it was serendipity, and del.icio.us played no role in the multiplication of bookmarks. In other case, it did (del.icio.us lets you copy other user's bookmarks). Unfortunately, it's impossible to tell which cases are which. It would be really interesting to know how many of these multiple bookmarks are independent discoveries, and how many are created within del.icio.us itself.
Second, I'd like to know who is most like IFTF. Who do we share the most del.icio.us links with? With whom do we overlap heavily in particular categories? I notice a few names turning up repeatedly, but I'd love to know whose collection of links looks the most like ours. Or shares a lot of our categories, but points to completely different things on the Web (in some ways, that would be even more interesting).
