Monoculture ahoy!

WebCore, the rendering engine, and also WTF, the web template framework, were identical five and a half years ago. Of course things have diverged massively in that time, and Chromium has reformatted all the code and moved it all around, but there is unmistakable common heritage.

Chromium is undeniably in better shape due to the multiple order of magnitude difference in manpower, but WebKit is still actively developed, strategically supports new standards, and can render most pages well. WebKit remains by far the better option for embedding because, unlike Chromium and Gecko, WebKit provides a system library with stable API and ABI.

If you're concerned about monoculture, support WebKit by using a WebKit-powered browser like Epiphany and reporting bugs. (Alternately, support Mozilla by using Firefox.) Or even contribute if you have the time and inclination: it's open source, after all, and it's quite a shame that there's almost zero developer community outside the developers from Apple, Igalia (my employer, we are hiring), and Sony's PlayStation team.
