Flying with a Wounded Wing: Why Twitter Still Has More Than a Chance

I agree with the basic premise (too much noise, the product needs to evolve) but I'm very frustrated because the author goes from that analysis directly to:

> The two major things Twitter needs to solve for are the algorithm of the dashboard (what content shows up in your feed and why) and length of tweets.

Why? I can see a correlation between the noise and the algorithm but the length? Why should it change? It feels like the beef of the analysis is missing.
