I’m currently researching:
- Twister: A fully decentralized P2P microblogging platform that uses the free software implementations of Bitcoin and BitTorrent protocols. See also this news story on Twister.
- YaYc: A decentralized web search application
- Peercoin: A cryptocurrency that claims to be more secure than Bitcoin, and to “reward users in more sustainable ways”
- Marble: An open source virtual globe and world atlas
Also some news stories:
- A fully open source laptop is under construction
- Here’s an excellent article about Bitcoin in the New York Times by Marc Andreessen
- Bitcloud: “wants To Decentralize and Revolutionize the Internet”
