Twitter is a different situation. Their previous biz was regular blogging. They thought higher-engagement audio blogging was the next step. They tried it and discovered it was not. Why? Because it took too much energy to create content. So they went in the opposite direction, again from the starting point of regular blogging, toward micro blogging (less energy, lower fidelity, whereas audio blogs are higher energy, higher fidelity). Since it was based on fundamentally different (in fact, opposite) assumptions than the business they had raised money for, they offered all investors their money back and created a new legal entity to keep the paperwork clean. That is not the same as being distracted by a flashy idea, where you have neither good evidence that your current idea is bad nor concrete evidence that the upcoming idea is an improvement. The article is also talking about jumping to ideas unrelated to your current focus, which aren't able to leverage what you've already learned and built. Twitter was invented entirely in response to what they learned from their experiment with audio blogging.
