What gets in the way
What makes releases risky
All or nothing
A new feature reaches every visitor on day one, so a problem reaches them too.
Several changes at once
A redesign changes five things, and nobody can say which one moved the number.
Peeking
Checking results every day and stopping on a good one inflates false winners.
