Before it was considered cool to tweet information to the world, SAS users who were hungry for inside information came to rely on a Little Birdie -- as in "a Little Birdie told me..."
sasCommunity.org has a nice history of the Little Birdie. The article mentions the "Jurassic period"; does this imply that maybe this birdie was a bit of a dodo and is now extinct? Certainly not.
As a colleague pointed out to me, Spring must be upon us as we can see the Little Birdie recently cited on SAS-L, talking about his/her favorite topic: SEEDs.
