Ron Amadeo has written a real tale of woe for Ars Technica:
Google Talk, Google’s first-ever instant messaging platform, launched on August 24, 2005. This company has been in the messaging business for 16 years, meaning Google has been making messaging clients for longer than some of its rivals have existed. But thanks to a decade and a half of nearly constant strategy changes, competing product launches, and internal sabotage, you can’t say Google has a dominant or even stable instant messaging platform today.
