Added description for WorldLingo

  [http://www.wikia.com/wiki/Wikia Wikia] hosts its user and keyword databases on a cluster
of 7 machines.
+ [http://www.worldlingo.com/ WorldLingo] - The !WorldLingo Multilingual Archive. We use HBase
to store millions of documents that we scan using Map/Reduce jobs to machine translate them
into all or selected target languages from our set available machine translation languages.
We currently store 12 million documents but plan to eventually reach the 450 million mark.
HBase allows us scale out as we need to grow our storage capacities. Combined with Hadoop
to keep the data replicated and therefore fail-safe we have backbone our service can rely
on now and in the future. 
  [http://www.yahoo.com/ Yahoo!] uses HBase to store document fingerprint for detecting near-duplications.
We have a cluster of few nodes that runs HDFS, mapreduce, and HBase. The table contains millions
of rows. We use this for querying duplicated documents with realtime traffic.
