Twitter could probably use some sort of light scoring which users have the ability to over-ride. Tweets can not be re-arranged outside of chronological order like Facebook now does.

There are different markets that need to be addressed.

For the "pro" users, Twitters is basically a two way news ticker. You follow people you need to communicate with, who are always doing interesting things, or who you need to hear from directly when something occurs. If you want to see the latest on VR, or WebGL, or whatever topic, following the right people on Twitter is pretty much unparalleled.

The second is the casual users. These are the 13-25 year olds who would have been using Twitter 5 years ago and have gone on to use Instagram and Snapchat.

When you split the pro group from the casual, Twitter's holes start to appear. Casual users post crap and they post a lot of it. On Facebook is gets auto-buried. One Twitter it doesn't. On Instagram and Snapchat users get to publish images and pictures that in most cases they created themselves. Even if a photo is noise, the user can scroll past it in a quarter of a second.

Whatever they do, they can't burn the pro user base. Those users are their moat. The casual users will be fought for continuously because casual social apps are more like fashion than tools.

Twitter has already made their feeds "intelligent"

1. Search defaults to what Twitter thinks are the "best" tweets for the search, not the most recent. 2. If there are tweets between 2 people you follow (where they are replying to each other), it will show up on your feed in ascending order. 3. They've now implemented, "while you were away" into your timeline which posts ~5 tweets they think you want to read, then when you scroll down you will see them again if they're recent.

I think it'd be pretty easy to offer both. A simple switch to turn on/off 'curation' or whatever.
