Broad topics we might want to look at

It would be interesting to see how voter turnout or other types of political participation differ between individuals with varying types of media involvement - social media, newspapers, television. Are those who participate in multiple levels more inclined to participate? Can social media help drive a political interest?

I agree that a key question would be where people are getting their news ie internet, tv, newspapers, and maybe in addition to that the company that provides it? CNN, CBC etc.

I think tweeting or joining groups could be considered part of political participation. It puts an individuals opinion in the public sphere for others to consume, can be seen as a form of online protest.
