Hakia, the meaning-based search engine, has added a new feature to its search site that lets users, who are searching for the same topic, communicate.
On the Meet Others page, you're able to add comments, or connect directly with the people on the page via anonymous e-mail or by Skype or instant messaging. It's also a built-in marketplace. People could post items for sale on the Meet Others pages. It's "Google with Craigslist," Hakia president Melek Pulatkonak told me.
The news link has some screens-clips of the new service as well. There definitely are advantages to collaborative searching. While the feature will not send the alarm bells ringing for major search engines, it's a good sign of innovation in the search space. Google has surpassed its competitors in this one arena, but that should not deter others from innovating in this space.
