One of the bigger challenges with anything having to do with software-as-a-service (SaaS) applications is how quickly they can sprawl out of control. Before most organizations realize it they wind up with multiple silos of SaaS applications that are even more difficult to integrate than traditional enterprise applications.
During the past four months we've seen not one but two well known real-time search engines disappear. First there was OneRiot, which in October 2010 decided to focus on advertising. More recently, Collecta closed it's real-time search engine and API to focus on alternative real-time products. Digging further into real-time search offerings you will also discover that crowdeye has also decided to pull its real-time search engine. This now appears to leave Topsy, and of course Google as the main players focusing on building a real-time search destination. Does this trend signal the end for all real-time search engines or just that their focus has been wrong?
