Dotspot: A widget-based article recommendation and commenting service

Got a problem with a news article? Dotspot’s widget lets you comment on an article on one site, then find related articles across the web where you can also leave comments and content through the widget. Sites install a line of code to get DotSpot working, which may limit expansion, but it can also be done on the server side. I’m not sure people actually use these sorts of widgets. Still, it’s a cool idea.

Angstro: The news that matters to you and your friends

You have a network of connections on sites like Facebook or LinkedIn. Angstro uses that information to determine the people who are most important to you. Then it recommends articles to you from your favorite sites, about you and your friends. The interface is similar to a personalized start page, like those offered by Yahoo and Google. The team includes Saleem Ismail, the former head of Yahoo web innovation outfit Brickhouse. Note: LinkedIn already shows you news articles based on how relevant the news is to you.

Live Hit: A recommendation guide for top content

The company collects data on what are the most popular and most up-and-coming pieces of online content on a site, then provides an interface to send users to that content. Data is found and incorporated into Live Hit every few minutes. Partner sites, including social networks like Picxo and content sites like MTV, can customize their own Live Hit interfaces.

Quant The News: Stock Mood pairs news and stock price to tell you what’s hot

Stock Mood, a product made by a company called Quant The News,  tracks articles about public companies, rates those articles as either positive or negative, then matches that data against stock performance. The result is a set of metrics including a moving average of “sentiment” (positive or negative articles) about a site, and mood, which compares the relationship between sentiment and stock price. This is a potential warning system if a stock is about to tank — or rise. With the many stock opinion measurement companies out there, like Cake.
