In December 2011, Microsoft first started its #DroidRage trend on Twitter asking people about their "Android Horror Stories" and then best(worst actually) stories got a free Windows Phone 7 mobile device as a consolation to their misery.
Microsoft is back with the same trend with same #DroidRage hash tag. They haven't mentioned the exact prize that is to be won but best guess is that it will be a Windows Phone 8 based mobile device this year. According to them, it will be a "get-well present" to help heal from the horrors of the winners.
If you have a Android Horror story, just log in to your twitter account and tweet it with the #DroidRage hashtag. Obviously, their are haters and abusers of this #DroidRage trend and quite expectantly these are Android fans. Android Central tweeted this not long after the above tweet from Windows Phone.
Its up to you whether to hate or praise Microsoft's marketing techniques and promotion event for Windows Phone platform but either way you can be a part of the trend by just tweeting with the #DroidRage hashtag.
