I've talked with Von Tetzchner and some of the staff at Vivaldi. I really think Jon is immensely underrated. Not only did he give us Vivaldi but he built Opera as well. Vivaldi was established as the direct desire to change the direction that Opera ended up going to.
At the end of last year I became a brand Ambassador for the browser. I really believe in the mission and values of the company. Jon is giving up a huge amount of profit by focusing on keeping the Vivaldi company one owned by the employees.
They have an excellent community as well. Their forums are extremely busy and well-moderated. Also if you sign up for a Vivaldi webmail account it comes with your own blog. The blogs made by the Vivaldi Community members are what some of what make up the Vivaldi.net homepage. It is powered by Wordpress and is a nice and simple alternative to paying for hosting if anyone wants to start a small personal blog
