Ever wondered what’s inside your camera? An exhibit at the German Technology Museum in Berlin shows a variety of cameras and lenses, all sliced neatly down the middle, so you can see their inner workings, in this photo gallery in Gadget Lab.

My first encounter with tagging was on Flickr. I discovered Flickr a few years ago when a colleague and I were chatting about emerging “Web 2.0″ websites. He thought Flickr’s photo sharing interface was a classic example. On Flickr people add descriptive “tags” to their photos. Two people walking on a beach might be tagged: beach, ocean, john, jane, sand, water, vacation, happy, and blue. At first I was bewildered. Tags seemed so disorganized, unstructured, and random. I didn’t understand why people bothered adding tags. How did they hope to use them?

Today I’m a tagging junkie. I primarily tag blog posts and web pages. What may seem like a primitive, even pointless personal filing system is becoming the “connective tissue” of the entire web.

Tags help manage information, but that’s just the beginning. They also enable collaboration, create opportunities for discovery, extend value through sharing, and I believe will impact the future of search.

If you’ve taken my advice to begin subscribing to blogs via RSS, adding tagging to your web 2.0 tool box is critical next step.
