The biggest mistake we made as a company was betting too much on HTML5.

The biggest mistake people make is to try to lose too much weight too fast.

The biggest mistake we made at WordPress.com in term of infrastructure was buying servers.

The biggest mistake to me is complacency.

Investors should invest on what they know. The biggest mistake is to invest on what they don't know.

The press keep asking me, 'What was your biggest mistake?' But if I had made a big mistake, they'd all be writing about it, wouldn't they?
