I find it very worthwhile to pay attention to what Opera does - and not just because it's my main browser of choice.
Opera has lonh been HIGHLY influential in the upper echelons of the browser maker world, as well as the standards world. With names like Håkon Lie and Ian Hickson involved, other browser makers watch Opera closely and have often copied their innovations - many of which have been ground breaking.
Multi-columns with CSS is something that website authors have needed for years. This support from Opera is a very hopeful sign for me.
