Not sure about Facebook since I never use it but Twitter's search feature is crippled because Twitter wants it that way. I think they are planning to monetize access to full history, though I dont remember exactly what was being said on this a week or two ago. When it comes to your posts and your stream I think you should be able to search it any way you want and cache it any where you want.

With a message bus foundation you wouldn't have most of the politics associated with group editing of articles which is where Wikipedia has its worst problems. The only places there would be a risk of politics at the Message Bus Foundation is in terms of use, abuse mitigation, spam filtering, censorship issues and interacting with intrusive government requests. When it comes to privacy and freedom of speech it should be designed to be as private and free as possible.
