How can we study the Arab uprisings (or if you want to call it the Arab spring) from a linguistic perspective? i want to find a suitable topic for my research thesis focusing on the Arab uprisings ( since it's one of the hottest topics today, i guess) but i still find it too broad

I've been thinking of exploiting the role of social media in these revolutions but it still needs to be further narrowed down and i can't seem to find enough resources on the internet about this topic. Please any suggestions would be welcomed !! TIA
