Nice flickr.com photo push app. I wonder if they will come out with a version in which you could program it to look for specific tags and also work as a screen saver. Other people's cats, whales, red things, anything.
It's interesting how one's experience influences how new innovations are thought of. Some get excited by the massive participation and possibilities for social change and communication others mourn the breakdown of standards as the masses take over. Others like a former AOL person who is working at the company where I am consulting took one look at the tags which I was excitedly showing him and just saw the possibilities for Spam. On that note Susan Mernit has a link to a very interesting post on Burningbird that is worth reading. It's about tags, folksonomy, flat databases, Clay Shirky, technorati and spam. There is something about tags and this essay that reminds me of an experience I had working with a BtoB directory publisher on a project and the idea that all of the world's catalogs would adopt a common standard of xtml. Order versus excitement, ease of access versus imposed systems.
