This unofficial Twitter Ruby gem is in its 5th version, and is heavily supported with documentation and code examples. Twitter Ruby Gem allows users to follow a user, retrieve a user name, fetch a timeline of tweets by a user, and many other functions. In this version of the gem, Twitter Streaming API is also experimentally supported.
Twitter today announced that it is launching a new offering that will give developers access to the full Twitter archive which contains all tweets going back to the first one posted by Twitter CEO Jack Dorsey in 2006. Previously, full archive access was limited to Twitter's enterprise customers.
Yesterday, WhitePages.com announced a new search API that gives developers access to a substantial database of 180 million people, which represents approximately 80% of US adult population and includes 25 million "at work listings".
