I think the hardest part is the content rules ( since all platforms have a learning curve). It should be the same as other social media.
Upvote = like to many users. So if you write " yo bro" i like it so you see i did read it.
Same for memes. Thats IMO a problem.
That's why the first impression is too important. Then afterwards, people will be more prone to give it more tries. Even if not the "comments" get upvoted, people know it needs to capture others' attention for it to happen.
I have totally verified this with Hivefest... first impression is ultimate. And in real life, too.
People don't try Hive not because they don't like Hive... it's because they don't know about it or have any relationship with it. So, they prioritise other experiences...
If the experience is UAU.... then it becomes a movement... trends, and everyone will check at all costs.
