About a month ago, I observed that two main things I found lacking here vs. Twitter were accounts from professional creatives (artists, etc) and discussion of breaking news.

The creatives have definitely started to arrive. But the breaking news has been much slower. However, it also seems like breaking news is starting to disappear from Twitter.

I wonder what will fill that gap. Perhaps it will be here, eventually.

Up until very recently, if there was something important going on anywhere in the world, it was virtually certain to be in my Twitter feed. Not just RTs of media reports, but discussion, etc. That just doesn't seem to be true any more over there. And it's not here yet.
I suspect this has much less to do with software features, and algorithms and more to do with culture and who's come over here.
@mattblaze I agree. There are folks who, because of expertise, etc, become natural nodes around which these conversations grow. As they appear here, so will the conversations, I think.
@mattblaze There also seems to be some reticence based on unfamiliarity with the concept and culture. To the latter element, I think some culture scolds have dampened enthusiasm for the twitter style, at least initially.
@jvagle another thing that seems to be missing (or significantly dampened) here is political activism, protest organization, etc.
@mattblaze @jvagle Actually I found a pretty good number of the twitter political/activist accounts I follow on here too using movetodon
