Communities - Web 2.0
I built my first community site back in 1998. Back then nobody
was talking about community sites or Web 2.0. It was a dating site,
but with a twist. The site was called Relation, and apart from the
dating part of the site, it also allowed the users to form
relations between each other (family, friends, etc.). What
linkedin.com and facebook.com does today, is what Relation did in
1998.
Today, almost all websites have some kind of user-generated
content, ie. comments from users on news websites, blogs, reviews
from users on amazon.com, etc.
Some websites are almost exclusively made up of content from the
users, ie. Wikipedia, YouTube and Flickr. All websites where the
content is user-generated, but monitored by site
administrators.
