As someone living in the EU who wants to use Threads but cannot - as Meta has blocked it here, while they work out GDPR compliance that has not been solved since launch - its amusing to me to read how Meta is planning to do various growth hacks.
My humble suggestion would be to first, perhaps, roll out to the EU? On one hand: sure, we are “only” talking about 450M potential users. On the other: anyone who has friends in this region or an interest in someone based here: well, that person needs to go to Twitter/Mastodon/BlueSky etc.
I am not saying this definitely explains all growth struggles: but surely doesn’t help true, global adoption?
