Yayagram
I only wish it weren't named Yaya, as I hate promoting the idea that old women are the pinnacle of technological ineptness.  I know that wasn't the intent, but still.  It's unfortunately a common expression to say "This product is so easy, even your grandmother can use it!"  As if the only group more incompetent than old people, is old women (or, if you prefer, the only group more incompetent than women are old women).I really think it's time to consciously move away from this outdated meme.
