We’ve talked before about Web 2.0 and its impact on everything from web design to March Madness brackets. Today, I present your life’s goals - 2.0 style.

One of the fundamental tenants of Web 2.0 is allowing website visitors to create their own content on the site and share it with other users, who can then comment, review, ignore, or whatever. The concept is called social networking.

The website 43Things.com does just that, allowing users to upload not their photos or video but their goals. As the site creator says:

We all have stories about what we care about. Writing down your progress on a goal can help someone else learn about something you both want to do. When you see a goal you’ve achieved, click on the “I’ve done this” button and share a story about how you did it.

Putting your goals online is intensely personal, and that’s just what this site is hoping for. Because if someone trusts a site enough to put their own personal goals online and share how they reached their goals with others, they will probably be extremely loyal site users. And a loyal audience drives ad revenue, which makes a site like this profitable.

Not only will they be loyal, but they will encourage other users to participate. They will create communities within the site, driven by shared goals. They will encourage each other and have very personal conversations, developing relationships they may not have anywhere else.

This is quintessential Web 2.0 — relying on the users to create content instead of just reading it.
