What was the maths.... well
I have 4330 followers (13/4/14 @10pm)
If each of my followers did just 1 RT a week of something I have tweeted or RT'd that would impact on their teaching, and I of their followers picked it up as well...
Then that is 4330x2 teachers I have had an impact on, making 8660 teachers.
Now if each of those 8660 teachers implements that 1 thing once a week for say 25 weeks of the year, then that is 216.5K mini impacts my original tweets have had.
Ok so we each teach 150 students a day, so say that change has a positive impact on 20 of them a day - so 100 student contacts out of 750 possible student contacts a week.
That is... 21650K student mini impacts the original tweets have had!
It really makes you realise what a difference a tweet and a RT can have...
