As you're well aware, Adrien (aka Pulkomandy) has been working for Haiku for several months now, improving Haiku's WebKit port and the browser WebPositive. Just yesterday, he posted another weekly update, number 36, detailing his progress. And his work has been well worth it and the improvements are clear as crystal.
But for his contract and work to continue, Haiku needs the funds and for them to have the funds, you have to step in, by donating. So, now that pay day has arrived (or for some of us, about to arrive), why not go to Haiku's donation page and show to them you want Adrien to keep working on this project? You know you want to.
