The main subject of this article is the condition of artificial languagesin contemporary social media. An analysis of the available statistics of YouTube, Wikipedia and Facebook shows the unwavering position of Esperanto as the most common artificial language. Other artificial languages, primarily auxiliary languages created in the 19th and 20th centuries, such as volapük, ido, novial, interlingua, interlingue, find their niches in social media, but their presence seems to be supported by very narrow groups of enthusiasts. Contemporary artificial language projects, such as lojban or toki pona are in a similar position. Although Internet is the natural environment for their development, they have not managed to gain wider popularity among users. Certainly, artistic languages embedded in well-known popular culture texts find a great resonance among the internauts, as shows the examples of Klingon and Sindarin languages mentioned in the article.
