Web 2.0 is everywhere. Nowadays you can't click on a link without stumbling across a blog, wiki, tag, RSS feed, networking site, digg button or AJAX app - even if you have no clue what those terms mean. If you are wondering about the manyfold Web 2.0 goodies out there, you might be interested in two of my recent posts in my own blog (Web 2.0 Essentials: What is it? and Web 2.0 Essentials: How to Get Started).
Today, I will concentrate on two specific Web 2.0 topics that are a little more abstract than blogs and wikis: Social tagging and bookmarking. As a recent Wall Street Journal article has demonstrated, this odd couple just came down from Mount Geek to the Mainstream Valley.
Tags - More Than Meets the Eye
Tags are a good example of metadata - data describing data, giving it structure and meaning. If book in a library contains data, then its reference card contains metadata - for example a book called "Delicious vegetarian dishes from India" might keywords such as "cooking", "lifestyle", "Asia" and "vegetarians". Tags are very similar to such keywords, as they describe web content in simple terms. The Black Belt Dojo site could be tagged "blog", "internal communications", "certification", "community", and so on, while individual blog posts could be described with more specific terms ("Liam's ramblings", "Sue's adventures"). The important point about these tags is that they are visible to readers (which, for those who know HTML a little, meta keywords are not - they are visible only to search engines).
So what? Well, the fact that tags are visible allows them to become a common language for those interested in the content. People writing about the same things will start using the same tags, and search engines will be able to pull these tags together into comprehensive link lists. Individual tags become social tags - a shared nomenclature to describe and find content. That's the secret of the great blog indexing service Technorati: Instead of analyzing content via programmed algorithms (as Google does), Technorati relies primarily on social tags to retrieve blog entries for you.
In other words: Tags allow communities to structure the internet.
Social Bookmarks: Shared Knowledge
Enter social bookmarks. Let's say you are working on several computers throughout your week: A desktop PC in your work office and a laptop at home. The websites you visit are often the same, so you need the same bookmarks on both machines - a cumbersome synchronizing process if done by hand. Luckily enough, there are services that allow you to store your bookmarks online: That way, they are stored on a central server accessible from anywhere in the world.
Once your bookmarks are stored safely online, you may have the desire to share some of them with a friend or colleague; in fact, some of your bookmarks are so great that you would like to share them with whomever you wants to know about them. So you strip your online bookmark repository from its privacy settings, so everyone can look at (most of) them. Furthermore you describe each and every one of them with useful tags - that way, they become clustered into categories and searchable.
Once the bookmarks are free for other people to search and access, a clever online bookmark service can make a ranking of all published bookmarks into a "bookmark hit list". They might even go one step further and allow these users to rate the bookmarks on their quality.
Voilà: Bookmarks + shared online repository + tags + ranking = Social Bookmarking. These services exist, and they are called del.icio.us, digg, reddit, NewsVine or StumbleUpon, and they - or rather: their users - are driving the way news are made newsworthy. That's the way internet buzz is created nowadays (or did you think that the cute video of a cat playing the piano was found by a FT reporter?).
Social Tags/Bookmarks and Internal Comms
Still there? Great, because social tags and bookmarks are relevant for internal communications, especially intranets. If a company gives its employees the possibility to tag intranet (and internet!) content, it will be much easier for them to find relevant news sources. Giving them the option to share their bookmarks will increase knowledge sharing without much effort and increase their productivity. Finance employees can share their links to currency converters, while production managers can post their favorite links to process optimization roadmaps. Intranets don't have to rely on machine-driven search results and can navigate the tags and shared links from their colleagues.
Ergo: Social tags and bookmarks are knowledge management in action.
Our Very Own Link Repository
For the internal communications community, I propose to share our bookmarks. I have set up a del.icio.us account for us blackbelts, to be found under http://del.icio.us/internal_comms. You can share your own bookmarks by including them (contact me for password info), or, if you are a del.icio.us user, you can share your bookmarks network with this group. That way, we can stay updated on great IC links through a simple URL.
