Timelope, Smallwords, Adaptiveblue, and Plurk.
Timelope
The Timelope, a personified Firefox plugin, eats your interwebs!!! We are currently in alpha (not even beta), so expect bugs and missing features. Want to store and sort your browser history (privately or publicly)? Want to follow others or have others follow you as you browse? Interested in endless links that are instantly linked together by keywords? If you said no to all of these questions, we didn't want you anyway, otherwise, sign on up and feed the Timelope. And no, Timelope may be both social and a network, but we are not a social network.
Smallworlds
The SmallWorlds beta test is an opportunity to invite people in to help us test SmallWorlds before we officially launch. This gives you the opportunity to take a sneak peak at what is to come, and gives us the opportunity to make sure that SmallWorlds is stable and the features are balanced and well received.
AdaptiveBlue
A Smarter Web is Personalized Web. Personalization is what helps you navigate through the myriad of choices. For example, if you rent movies from Netflix and your friend from Blockbuster, your shortcuts should be different. If you choose Last.fm and your friend likes Pandora, the browser should know this. And if you like buying from Amazon the Browser should help you do that instantly from any page on the web. This is the power of personalization.
Plurk
Plurk at the core is a micro-blogging site that allows users to post short messages similar to instant messaging, but charts the messages based on a time-line. The format is becoming increasingly popular with sites like Twitter and FriendFeed becoming more mainstream.
