Backlinking is perhaps the next revolution on web, after forward linking to different sites from a web page. Suppose I write an article. Say, some people read it and refer to this article from their weblogs or other sites. And I would like to know who all have done this type of linking (so I am able to read their views.) Now, either the web-based applications should co-operate (and this is easy when same application in all the sites), or a third party should visit both sites and somehow connect them. The latter is what is already possible on the web: The readers of the other sites will follow the link, and visit my site to see the complete article. In this process, sufficient information is collected and passed on by the browser of the visitor. This information is then made available in real time from my site.
Isn't that a revolution?
