"I don't know a single web dev who tests on Opera anymore."
Hi, I'm a dev who always develop for Opera. The reason: if it works in Opera it almost is working in all other browsers. And I ofcourse like Opera very much. I think it has one of the best interfaces and toolsets.
"They'll continue to be the browser that nobody cares about."
This is a very stupid statement. 300 million monthly users care about Opera. The HN "community" != the rest of the world.
