As you’ve probably heard, Opera has announced that they are abandoning their Presto rendering engine in favor of Webkit. CTO Håkon Wium Lie (you know, one of the guys who invented CSS) has stated that this will allow Opera’s resources to assist with the continued development and improvement of Webkit:
“It makes more sense to have our experts working with the open source communities to further improve WebKit and Chromium, rather than developing our own rendering engine further. Opera will contribute to the WebKit and Chromium projects, and we have already submitted our first set of patches: to improve multi-column layout.”
