The problem I have with Twitter is that it's too people centric. For example, I like to follow finance news, so I could probably find some Twitter accounts that post about that. But surely the people running those accounts would also post about other interests they have besides finance. I probably won't really care about their other interests so all of their non-finance related posts would just be noise in my feed.
On the other hand, there are topic centric social networks like Reddit where it's a lot easier to find and follow just the news about a specific niche (like finance).
I'm not totally against the people centric model. I think it can work well in social networks like Facebook and Instagram that are more friends and family focused, but I don't really get that vibe from Twitter.
