Tonight, the head of the program, Gabe Aul, tweeted out that they are giving away a prize to random Windows Insiders. While he did not say what the prize was, as you can see from the top comment on this post, it's a trip to Mobile World Congress.
If you open up the hub, you may see the offer to enter for a chance to win tickets to Mobile World Congress in Barcelona. Per the disclaimer, the price is worth $2498 and is being offered worldwide.
