  Collecting good ideas is vital for organizations, especially companies, to
retain their competitiveness. Social media is gathering attention as a place to
extract ideas efficiently; however, the characteristics of ideas and the
posters of ideas on social media are underexamined. Thus, this study aims to
characterize spontaneous ideation contests among social media users by taking
an event of Facebook's name change to Meta as a case study. As a dataset, we
comprehensively collect tweets containing new acronyms of Big Tech companies,
which we treat as an "idea" in this work. In the analysis, we especially focus
on the diversity of ideas, which would be the main reason for enlisting social
media for idea generation. As the main results, we discovered that social media
users offered a wider range of ideas than those in mainstream media. The
follow-follower network of the users suggested that the users' position on the
network is related to the preferred ideas. Additionally, we discovered a link
between the amount of user interaction on social media and the diversity of
ideas. This study would promote the use of social media as a part of open
innovation and co-creation processes in the industry.
