The author seems to imply that "winning" here correlates with a measure of posting frequency:
>If Bluesky comes out as a “winner” and more posting happens there, I think I’m generally fine with that. At least for now.
If that's what the match between microblogging services is about, I wager Bluesky has no chance whatsoever to come out the winner. It sounds like wishful thinking to me. Mere delusion.
