Taufik Rosman Malaysia The 2023 Wikimedian of the Year, Taufik has been editing since he was 8 years old. He has expanded the Malay Wiktionary with nearly 11,000 changes. “Each of our contributions matters greatly,” Taufik says.

Thanks to her, Wikipedia has information about all of New Zealand’s 1,800 endemic moth species. Armine Aghayan-Flisch Switzerland Writing a Wikipedia article each day for a hundred straight days is a feat.
