I think the biggest mistake I made was this wretched ability to see both sides of an argument.

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

I think that people on both sides of the aisle are rejecting what's going on with Washington and the establishment.

The biggest mistake to me is complacency.

Both sides should demand a speedy trial.

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