SiteChatrSiteChatr is a Google App Engine application and Firefox browser extension that allows users to make comments, much like a message-board system, directly on any public webpage. The chat history for a particular webpage will automatically appear on the side of the webpage when a URL is loaded in the browser.
This differs from other message-board systems in that:
Users are not required to register on each website Independent from the host of the webpage being commented on News "aggregator" sites like slashdot.org, digg.com, and others require users to browse away from the original article to place comments The downside is, of course, that it requires a separate browser extension.
ChallangesOne of the main concerns is correctly pairing a unique webpage with it's chat history. This is complicated when the URL of a webpage may change (due to archiving, domain name change, etc). An algorithm will be required to calculate the similarity of the requested content compared to what is already known to the application. This is similar to comparing the similarity of student-written papers or code. There are a number of publications outlining processes for similarity-based search. Additional work will be needed to acheive this with webpage content containing messy HTML markup.
Furthermore, hosts may cease to exist or a particular webpage may be removed from the host entirely. In this case chat history can be viewed on this application's website much in the same fashion as the news sites mentioned above.
