Why we need a new twitter?

Twitter has become a garbage dump. Even though I don't follow many controversial people, still tweets, re-tweets, promoted tweets finally results in my timeline being full of garbage. So I am wondering what is the solution. There is still sufficient information that comes on my timeline that I am interested in but it is becoming more and more difficult by each passing day to decipher good information.

As a rule, I block anybody who I am not interested in. I have nothing against anybody who wants to say something, I am just not interested in spending my time in listening to it. Still some of my friends are interested in what others have to say and most retweet without thinking. That garbage shows up in my timeline.

So I am thinking what is the solution. Here is what I propose.

We need a cross-breed of Liinkedin and Twitter. What we need is the social graph of the LinkedIn with the degree of separation and approval and the broadcast capability and ease of use of twitter.

• The edges  in social graph has to be directional. Basically, if I am interested in listening to what somebody has to say, that doesn't automatically mean he is interested in what I have to say.
• I only see messages from my direct connections, if somebody else wants to reach me, he has to go through the message forward model of LinkedIn
• Promoted messages should clearly mention which of  the attributes of my interaction are causing that particular promoted message to show up in my timeline.
• If a person is blocked by a specified number of people, he is automatically thrown off the system. Basically we need an algorithm to locate people who are paid to abuse.

What say guys, somebody wants to build it. Or better still, fund me I will build it. I will call the system Cricket and a message would be called Chirp :-)
