I have launched a contest for testers where there are various contexts set and you got to answer them in the blog post commenting section itself. I need not mention more of the details here. You can just deep dive in to http://tuppad.com/blog/2012/03/14/an-awesome-test-for-testers-take-... if you want to take the challenge.
There are 3 prizes as well. All the best.
