"I know how long and how much thought it takes to write a post like this. A few years ago I decided to write a deck about Javascript  closures and put it on slideshare (mainly so as not to forget the things  I'd learnt). Needless to say, it got very few hits and I was disappointed. Then someonemust have noticed it and spread the word, so the hits went up - and I felt better.It' always nice to have your work noticed." - David Semeria
