I just got the t-shirt, diploma and two stickers for my participation at the first Google Highly Open Participation contest. The t-shirt is a bit big for me (I thought that american L size is the same as european one, but seems it’s not). On the back it says “I power Open Source”.
I enjoyed participating, it is a very good idea both for open source projects and for high school students to get involved in open source. It is a very good introduction for Summer of Code.
It was the first edition but I hope more will come, I will surely participate next year. There weren’t many projects participating but perhaps next years more projects will be involved and a bigger variety of tasks will be available.
