Seems like the hard truth is all these alternate platforms that offer their technology as the reason to get on it ... it's just not a great selling point for someone who wants to post "woah watch out driving tonight, it's slippery out there" or cat pics. I think that's a lot of users.
The content of the posts and some level of moderation is the selling point.
Personally that's kinda a bummer, because IMO my biggest disappointment is that its just Twitter but little different. Same pithy posts and petty bickering:(
