I blogged in December about how fast growing web sites are often fueled by user content. Users post content, which attracts more users (as search engine index this content), who in turn post more content.
Today I discovered a new Idealab company called Insiderpages that is focused on the local yellow pages market. All the local listings are created by users. "The yellow pages written by friends", it says. Launched in November, the site has a 1 week Alexa ranking of 50,000, which is excellent for such a new site.
Another new site that lives on user generated content is 43things.com, a site apparently funded by an investment from Amazon.com. The site has a 1 week Alexa ranking of 9,620. That is extremely impressive. The site has recently gotten a ton of media coverage, primarily because of its connection to Amazon.
43things.com, like deli.cio.us and flickr, uses "tagging" — a new term that describes how every keyword that a customer uses to describe a photo, a web site, or a goal (or whatever object they are commenting on) becomes a tag that other customers can click on to find all other objects that also use that keyword.
I think the difference between the terms "tags" and "keywords" is that the term "keywords" primarily describes search engine queries while the term "tags" is used to identify metadata about content — and the metadata is used to create navigation links for other users.
Here are the most popular tags at 43things.com. They use tags to help people find other people with similar goals.
I’ve only discovered the term "tagging" in the last couple of weeks, and I haven’t yet built any sites that use tagging; but I think this is going to become very common on the web. I’m adding the term "tagging" it to my Google News Alerts keyword list so that I can see how other companies use it in conjuction with user generated content.
