This just gets better and better, there are few things we can learn here:
 

• The market for real-time search is very strong and is very demanding.
• Even the big players are struggling in this area as their current processes do not meet the requirements of the real-time search.
• Although it may address the real-time search in short term but relying on one source (no matter how big is the source) is in contrary to the concept of the real-time search.
• They have to have these deals with FriendFeed, eBay, Craiglist, Amazon, AOL, Typepad, Livejournal, Digg, Delicious, all web forums, discussion boards... and many more who publish user generated content to meet the real-time search demand in global scale.
• Real-time data and corresponding search capabilities on the web can not be dominated or owned by one or two sources, it is against the non-centric nature of the web.
• Other mechanisms and standards that are publicly available and follow the non-centric nature of the web will eventually replace the centralized, privately owned and operated real-time search processes.

 
Those who can successfully demonstrate a non-centric, comprehensive real-time search capability that is built on top of existing technologies and standards are all-time winners.
