One day, two new rendering engines announced, three browsers involved!

When you wait ages for a bus, and then three come along at once, it's not a coincidence: it's a side-effect of queuing and traffic lights.

But what about when three browser vendors make announcements on the same day?

Robust competition? Serendipity? Coincidence? Or a bit of all of them?

Google announced Blink, a fork of the Webkit browser that aims to build a smaller and safer rendering platform based on what Google is unashamedly referring to as a "healthier codebase."

Opera, which is retiring its own rendering engine Presto and replacing its browser core with Chromium, the open-source flavour of Google Chrome, indirectly announced its commitment to the Blink-based flavour of Chromium.

And Mozilla announced Servo, or, more accurately, announced an ARM port of its experimental browser engine Servo, written in its new and experimental programming language Rust.
