Social media and group activites

Well after reading up on last weeks class I feel I have really let the team down with the task and would like to do my own assesment task as it is not fair that they have done all the work. I dont know if this is possible but i will sort something out.
I have decicded to do my social media presentation on Blogger + Twitter, I know I already had Twitter prior to this class but I only ever read the posts never really posted so I am going to attempt to broaden my knowledge on it!
