This is on of my favourites.

* It is neatly packaged, wonderful UX and a little sweetening of humour that makes it palatable to the layman

* It gives code examples that provide a little bit more in-depth exploration for the enthusiastic or aspirational novice

* It has a nice structure such that single exploits can be shared. For example, after a client of ours was hacked via a SQL injection on their website, we were able to show them the SQL injection exercises to demystify the topic a little bit and to make it seem less intimidating

* It's a great go-to starter. When I go to schools for careers fairs, I always give this link out to kids who are interested in security work.
