Cool idea, am working through.
It's annoying that you need to click 3 times per question, and the buttons are in 2 different places.
Maybe would be better to just let me click the answer I want and then instantly show me the next question?
Also who is Sandi?
Sandi Toksvig, the current host of the BBC program QI (Quite Interesting), previously hosted by Stephen Fry. She's also been on a number of other BBC TV and radio shows.
I suspect Sandi Toksvig, one of the hosts of QI. One of the 'success' messages is "quite interestng!".
No offence mean to anyone, but the whole exercise feels very QI : superficial 'understanding' of a large range of things (for example words) without much of a connection between these words.
