I grew up in the Web 2.0 revolution and like most people in the last 10 years I participated in this explosion of user submitted information by writing in wiki posts (www.neuralwiki.org), blogs and forums.
But as anyone familiar with Web 2.0 knows, there is a limit to the usefulness of this data with our current search technology. For example, searching for a term that I dont know or a concept that I cannot formulate into words, is a frustrating effort. The other problem is the orgy of information. Searching for a common topic can actually be worse than not knowing what you are searching for when millions of websites match your search query. Which one to choose, and how do I know that the website that is most helpfull isnt just one more GOOOOOOOOGLE search page away.
Sifting the massive amounts of information is absolutely essential, and will fall into the realm of Web 3.0. This technology will search through data not looking for keywords, but key knowledge signatures. This is how the new search technology will help find the most relevent data, by matching knowledge signatures.
The most amazing part of this technology, especially as a scientist, will be the ability for your own work to generate a knowledge signature that that can be matched up with other papers as they are posted to the web and other work that you have created.
So here's hoping for some awesome Web 3.0 apps
