I can't stand Facebook and refuse to have an account with the service, despite the continuing trend of many companies requiring an account for one thing or another, but if they were to buy Opera then that would mean they also acquire FastMail; my current email service. Over my dead body would I entrust my emails to Zuckerburg and his company.
