Blog post draft describing 2014-10-30-toronto workshop

Needs contributions from other instructors and general checking..
Did we have a checklist for Python learners? I don't remember if we did, but it could have helped avoiding this issue. Learners in the back also had trouble reading the text (can't zoom in much because we would lose the view of the whole page that way). 
I suggested screen sharing services like join.me, but I think Greg had other concerns in addition to the WiFi bandwidth.
