I was quite touched even though I know the birthday wishes come from cold electronic circuits Anyone know how long Google has been doing this? Did I miss it in previous years or is this a new thing?
A birthday wish but no gift, huh? Man, I can’t imagine how that must feel. Hey, just remember, it’s the thought that counts. 
It was announced on October 16, 2010. This is not the first time someone has posted about it here.
Edited to say Happy Birthday!
