You have an undergraduate degree and are about to obtain your graduate degree. Despite your stated lack of experience, with all that education you refer to IS as a "general field" and you can't independently decide on a specific topic for a research project?
Part of being a practitioner of the dark IS arts is keeping up with what's going on and participating in the professional community. By now you should have at least four or five subscriptions to industry publications and be a member of at least one or two industry groups. Those sources would provide a wealth of ideas...if you were taking advantage of them.
You might want to think about showing a little more independent initiative and not taking the easy way out, which you've done by soliciting ideas in this forum. What I would have done were I you is develop four or five ideas, then post to this board and ask for feedback. Don't ask others to do your work for you.
Sorry if this sounds a bit harsh but sometimes the best thing you can do for someone is throw a bucket of cold water in their face. Time to wake up.
