The great thing about WordPress is that, as an open-source and community-built platform, anyone can contribute code to it. Whether it's small fixes, or big new features, patches can be submitted by anyone and everyone. Once such patch that I submitted was an improvement to the existing export tool that is built into WordPress itself. Unfortunately, that patch has not been merged into core yet and I'm not sure when it's going to be, so in the mean time I packaged it up as a plugin.
