  Social media has grown exponentially in a short period, coming to the
forefront of communications and online interactions. Despite their rapid
growth, social media platforms have been unable to scale to different languages
globally and remain inaccessible to many. In this paper, we characterize Koo, a
multilingual micro-blogging site that rose in popularity in 2021, as an Indian
alternative to Twitter. We collected a dataset of 4.07 million users, 163.12
million follower-following relationships, and their content and activity across
12 languages. We study the user demographic along the lines of language,
location, gender, and profession. The prominent presence of Indian languages in
the discourse on Koo indicates the platform's success in promoting regional
languages. We observe Koo's follower-following network to be much denser than
Twitter's, comprising of closely-knit linguistic communities. An N-gram
analysis of posts on Koo shows a #KooVsTwitter rhetoric, revealing the debate
comparing the two platforms. Our characterization highlights the dynamics of
the multilingual social network and its diverse Indian user base.
