  Increasingly, alternative platforms are playing a key role in the social
media ecosystem. Koo, a microblogging platform based in India, has emerged as a
major new social network hosting high profile politicians from several
countries (India, Brazil, Nigeria) and many internationally renowned
celebrities. This paper presents the largest publicly available Koo dataset,
spanning from the platform's founding in early 2020 to September 2023,
providing detailed metadata for 72M posts, 75M comments, 40M shares, 284M likes
and 1.4M user profiles. Along with the release of the dataset, we provide an
overview of the platform including a discussion of the news ecosystem on the
platform, hashtag usage and user engagement. Our results highlight the pivotal
role that new platforms play in shaping online communities in emerging
economies and the Global South, connecting local politicians and public figures
with their followers. With Koo's ambition to become the town hall for diverse
non-English speaking communities, our dataset offers new opportunities for
studying social media beyond a Western context.
