That's right yet another big dollar company, Instagram, is using Linux for it's servers.  If you are a regular reader you already knew that right?  We came across this article and thought it was worth pointing out again given the valuation Facebook just paid for them.  As the article points out they were just sold for $1 Billion Dollars but Connanical itself isn't valued at even close to that amount.
