Twitter is a very simplistic core. Around that core is a whole ecosystem that adds value to Twitter. You have a large choice of &#8220-Twitter clients&#8221-, and there are plenty of websites out there that complement the basic Twitter service.

It is the anti-BetFair case. The future prediction exchanges will be built around a simplistic core, and there will be plenty of add-ons and complimentary services &#8212-all of which will be optional, so as not to scare off the newbies.

From today&#8217-s New York Times:

Studies by Mr. Nielsen’s company, the Nielsen Norman Group, an Internet design firm in Fremont, Calif., show that only 50 percent of Web visitors scroll down the screen to see what lies below the visible part on their PC monitor. “Users spend 30 seconds reviewing a home page,” Mr. Nielsen said. “A business must encapsulate what they do in very few words.”
