While I doing Web2.0 presentation in my company, I mention Tagging is heart of Web2.0. People used to ask me what tagging service could impact enterprise business and people’s life. I’d like to point this to Flickr, who introduced Tagging to Web2.0.

This simple URL shows the “tag cloud” in front of us. What do you see? What kind of information do you receive? Simple, eh? The bigger the font of tag is, the more popular such topic is. Go to http://www.flickr.com/photos/tags/ then click around. Seems “family” is the most active tag used. Does it tell you what the majority people think or care?

Oh, and “party” one… If we compare “canon” and “nikon”, “canon” looks a little bolder than “nikon”. That indicates the pictures loaded in Flickr.com were mostly captured by Canon camera. Let’s look at “london” and “paris”, “london” is bigger, and even “paris” is a little bit bigger than “newyork”.

Go to Flickr.com and see by yourself. I have my photo gallery too, but without tag.
