Chimera developer Mike Pinkerton has posted a somewhat despondent blog entry about the future of that project: "...I'm torn about what to do with Chimera. It's obvious it will only ever be a marginal product on a even more marginal platform..." MacSlash has an active thread on the subject. It would be disappointing to see Chimera stall out, as it's already a great browser and the nightly builds have continued to add features and stability. It would be especially bad to see Safari starve out its best competition, because there's no guarantee that Apple's won't just drop the ball at some point in the future. (Meanwhile, the developers of Omniweb are considering replacing their renderer with Apple's WebCore, which powers Safari).
