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 suspect that the lack of quote-post/tweet has an impact. Boosting news directly seems a little silly/redundant as the news is news and those interested will follow the appropriate sources.
But boosting without being able to add commentary seems somehow less appealing since you’ll want to explain *why* you think this thing is important (or stupid). It adds a tiny bit of friction that slows things down if you need to compose your own message linking back to the source.

@erik @mattblaze This is interesting - I agree with you, but it's purely my personal take on QT'ing. On the bird site, I used QT drastically more than RT to do exactly that: Explain to my audience why I was sharing something, instead of just saying "here, see this"

(I understand the abuse-centric arguments against QT and I'm not trying to argue one way or another, just agreeing with the observation)
