Playing tag with blue people. Socially augmenting employee profiles with people-tagging

Socially augmenting employee profiles with people-tagging, is an article put out by the people at IBM concerning an experiment they ran on there own Blue Pages (Think IBM's personal Facebook), where you could tag people. In an effort to keep things friendly and useful, there are only public tags, and tags you put out can be easily traced back to you. The effort is to try and improve blue pages with relevant information. If a person has a lot of people tagging him with "good java experience" or something like that, you can easily find people like that within the orginization, even if there job doesn't necessarily imply that. Not all the tags were work-related of course, humourous ones such as "needs to shave" still popped up, but still interesting. In the future they were thinking of making private tags, so that you could sort through your own contacts fairly easily. I personally like the idea of being able to tag people with features, and being able to electronically store things they can do. I don't think I would want it in a purely social medium, such as Facebook, but in a workplace setting this could be a valuable asset for finding the right people, especially in larger companies.
