Bram Moolenaar is the creator and maintainer of Vim. He has been working on it for 27 years, and has no plans to stop improving it, thanks to the many volunteers who provide patches and test new versions.
After studying electronics and inventing parts of digital copying machines, Bram decided that creating open source software was more useful and fun, so he worked on that exclusively for several years. He currently works for Google, one of the few companies that fully embrace open source software. In between, he did voluntary work on a project in Uganda and is still helping poor children there through the I Care Children Foundation(ICCF).
I would like to thank all the Vim developers for helping me make Vim into what it is today. Without them, only a fraction of the features would have been implemented and the quality would not have been nearly as high. I would also like to thank all the plugin writers for building on top of Vim and making complex features available to users (so that I don't have to!). And finally, I would like to thank Ruslan for writing a book that not only aids users with Vim's built-in features, but also with getting to know and use plugins.
