Here is where they loose the traders:
They need a redesign for layman consumption. Filters! Images! Curation! (Sounds like Yahoo, and this is why Yahoo has +430M MAU.) I think twitter gets this, as they purchased gnipe.
As twtr approaches the $20 billion market cap, the stock becomes interesting. What would be even more interesting would be a merger between Twitter (content distribution) and Yahoo (content consumption). The two would absolutely rival Google and Facebook. (That would be awesome.)
