Localizing WordPress Themes and Plugins
It would be easy to assume that everyone on the internet speaks English. The majority of software is produced in English simply for the reason that doing so gives it a larger potential audience (or, maybe more appropriately, gives it access into the American market). However, you shouldn't assume this means everyone reads and writes English at the same level, or that non-native speakers wouldn't want software in their own language. There is a world of speakers outside of English and now is the time to tap into them.
