HP has posted a page promoting WebOS for developers. "We have an awesome independent developer community in webOS Internals that does things like replacement kernels, new system services, and overclocking tools. Our community produces innovations that have made their way into later webOS releases; for example, we liked the page cache compression work that they did to improve webOS 1.4.5 so much that we made it part of our standard Linux kernels on webOS 2.0. HP hasn't tried to stop or silence these groups; instead we work with them when possible and even give them hardware to help with their explorations."
