Sometimes it takes a while for me to learn something, but when I do ... whamo, I am all over it! That is the case with Angry Nerds. This past April 1st, Atlassian created the perfect April Fools joke, Angry Nerds. However, the response was so great, you can actually "play" the iPad / Android game (no fooling). When you link to Angry Nerds, make certain you click upon the nerds in the game viewer!
Finally, I had to create my own Angry Nerds ... circa the Northstar Nerd (see below)!
Oh yes, Atlassian makes a good wiki, Confluence, and this was extremely smart marketing!
