Last weekend I had a chance to quickly hop on the stage of the Mozilla devroom at FOSDEM and demo l20n to the audience.
It was a really cool moment for me. I've been involved to some extent in the project from its early stages, but only recently have I started contributing code to it.
My talk was a quick introduction to how l20n will look like from the developer's and localizer's point of view, with a couple of examples. With all the work on HTML bindings that Gandalf's been recently doing, I was actually able to demo the examples running in the browser.
Check them out at http://informationisart.com/preso/fosdem2012/.
I've also created a short screencast that will walk you through the demo. It's only 14 minutes long.
I hope you'll enjoy l20n as much as I enjoy working on it!
