Google has apparently killed off its Realtime search feature, or disabled it for a while, at the very least.

Google’s recently unveiled social network, Google+, brought a host of changes with it, including a cleaner-looking user interface.

An unexpected casualty of these changes may be Google’s Realtime search, developed to integrate real-time data from Twitter (as well as blogs and other social networking services) into a Googler’s web search.

According to Search Engine Land, the Realtime option has disappeared from Google. The feature’s URL leads to a 404 error page, and the option is missing from Google’s left-hand toolbar. And tweet results no longer appear under recent News query results.
