My list of 2005 predictions included the following:
Google releases "Google Forms", a way for people to share structured documents with each other. This could be used to share contact information, resumes, matchmaking information, medical records, etc. and would include security permissions so that users could restrict information to, say, their current doctor or to their friends.
In addition, I wrote a much longer blog entry about this idea here. According to buzz on the net, Google has indeed created this product, although it is called "Google Base" instead of "Google Forms". Because it's not official, the product could of course just be a rumor, but I doubt it. Some screenshots are here and here.
