On another note, last year Twitter open sourced Gizzard. http://engineering.twitter.com/2010/04/introducing-gizzard-f... (ironically, nobody seems to have tweeted this article!!) Natural curiosity-I downloaded the repo,and tried to understand what it was. Later,it also seemed the buzz surrounding ( on HN atleast) didnt last much, and I forgot about Gizzard completely. Are there startups/bigCos using Gizzard,other Twitter's open source stuff?
