Our eracism project form for setting up projects was taken down for terms of service violation. If you're collecting emails in a google form, you may get suspended. This is the second time. I suggest you collect emails, etc in forms other than google docs for this reason.
Here is a storify by Steven Anderson (@web20classroom) who had asked the difference between Macbook Pro vs. Mac Air. Storify lets you easily link together information from Twitter, Facebook, and other social media in an easy-to-read story. Just remember to do it pretty soon after tweeting as it can be hard to get back to old Tweets. Twitter doesn't let you go back indefinitely. Great comparison and view of how social media mavens like Steven can share information from their networks.
