Weibo is None of the above.
as @EmilAbraham commented, define biggest- by number of monthly active users, Weibo is already bigger than Twitter/X (582 million vs 541 million)
@NathanpmYoung how do we trust twitter's numbers then, there are tons of bots on it

https://www.statista.com/statistics/272014/global-social-networks-ranked-by-number-of-users/ there are conflicting numbers for twitter actually
@NathanpmYoung weibo is quite twitterlike, probably as much as the other sites, it may even be closer to former twitter than current twitter
“Twitter still the biggest social media of it’s kind” and “Twitter much smaller but nothing bigger than it” are not mutually exclusive
Bump (does this bump)
