Yahoo bought del.ic.ious yesterday. Predictable. A VC delight. A pity. Delicious was a tag aggregator. Tags, search and feed are the way the web is starting to organize itself. On the net, it's increasingly hard to find things because there's so much "stuff". So Google and Yahoo and others are search. There a ton of feeds emerging to shape individual content. And putting names on posts and content, tags is increasing. Hence you can search for a tag, on a photo, post, newspaper, piece of content, stock quote whatever and get some reasonable specific content back.

At its simplest, Delicious allowed individuals to aggregate their tags and others to look at them.

What has made Google special? And cool?. They keep introducing new ideas that extend and develop search. In the process they  smash a host of established industries and ways of doing things. Efficiency coming through. Valuable new ideas emerge.

Delicious sold too early for that too happen. It's not refined enough. Hasn't challenged enough. It's still raw. Yahoo will now integrate it and shape it into a corporate entity. That's going to be good for now. And for Yahoo. Not so good for ongoing disruptive and exciting new ways of doing things.
