OneTrueFan, San Francisco, California, United States Active

OneTrueFan brings to light the communities that already exist at your favorite sites.

Install us in your browser and show up everywhere. Install us on your site and get everyone to show up.

"In its current form, the Web is a largely uninhabited world, where people can only see each others' artifacts and the vast majority of us never leave an imprint on our favorite sites.
OneTrueFan was born out of two ideas: 1) experiences are better when shared and 2) changing human behavior is next to impossible. Our first service enables people to automatically show up on the pages they visit. Other people can then discover them and interesting new content.
OneTrueFan is not a social network in the traditional sense, in that social networks attempt to localize an experience and/or lock users into a single social graph. OneTrueFan is the anti-network, bringing to light the communities that already exist at your favorite sites, with no additional effort on your part."

Open Virtual World

Our goal is to create a virtual world client similar to rocketon or weblin – but under open source licence and for all operating systems.

We are creating an open system. The software will be available with an Open Source License. We do not believe, that we can sell the client or server software. Therefore we publish everything and use the benefits of Open Source in return.

Of course, later we have to earn money to operate some servers at least. We will create and offer virtual goods. You will be able to get virtual resources, to craft virtual goods, to trade, use, and sell them. We will also sell additional virtual goods, which you can use to craft even better virtual items. But you do not have to. The system will be open and free to play.

We strive to create an open virtual world on the Web similar to weblin and RocketOn, but better, richer, more important, and more open for your participation. We do what weblin could have done. We think what weblin did not think of. We have more ideas than they had. We plan what weblin did not plan.

The open virtual world will be THE virtual world on the Web. It will be open just like the Web with millions of clients, and servers, and many services. We will create services for you and we hope, that other people will do the same. We believe, that competition makes this virtual world as interesting and diverse as the Web itself.

Turning the Browser into a Social Network

From their description:

"The Coop is a Firefox addon in development that will let users keep track of what their friends are doing online, and share new and interesting content with one or more of those friends. It will integrate with popular web services, using their existing data feeds as a transport mechanism. "

"Users will see their friends' faces, and by clicking on them will be able to get a list of that person's recently added Flickr photos, favourite YouTube videos, tagged websites, composed blog posts, updated Facebook status, etc. If a user wants to share something with a friend, they simply drag that thing onto their friend's face. When they receive something from a friend, that friend's face glows to get the user's attention."

Surfing the web is like travelling alone. You get to see beautiful places, funny places, interesting places, yet they all have one bad thing in common: nobody's there.

Of course it only seems so. There's people visiting the same place you're visiting: reading your blog, listening to music you like, checking out the same movie, the same book.

Wouldn't it be nice if they were just a click away?

Now they are.
