-Name three industries mentioned in article that are being dramatically changed by twitter.

 The phone telecommunications industry, the internet industry, and the news industry.

 -What is #hackedu?

 A daylong conference attended by Johnson created an interaction in and outside the conference room. The theme of the conference was reimagining how education should look in a web 2.0 world. Hacking Education was a small, private affair with “40-odd educators, entrepreneurs, scholars, philanthropists and venture capitalists, all engaged in a sprawling six-hour conversation about the future of schools.”
At the beginning of the conference, those who were posting live commentary about the event via Twitter had to include the word #hackedu in their 140 characters. A hashtag facilitates the grouping of events or topics and the #hackedu was the hashtag they used on twitter to hold discussions about the conference’s topic. Originally the tweets were created by the conference participants, but within half an hour as Johnson indicated, the word began to spread to the Twittersphere.

-How is real-time search affecting search engines? What moves are search engines doing as a reaction to growth of real-time information and search?

 The search engines are not particularly useful solutions for finding out what people are saying at the moment. As Jhonson puts it, Twitter is a” more efficient supplier of the super-fresh Web than Google.”  The search engines provide results of more of article research kind of stuff whereas twitter provides comments made by regular people on certain topics. Twitter is more subjective whereas the search engines like Google have more of an objective approach. Real-time search is competing with the search engines that even Evan Williams Twitter’s co-creator with Biz Stone have” turned down a reported $500 million from Facebook”. Recognizing the threat of Twitter, Google prepares to launch a service that indexes and ranks content from micro-blogging services like Twitter. This new product will sort results by relevancy, will be integrated with standard Google search, and will appear based on frequently-used keywords or current events. Google also has talked about partnering with Twitter on real-time results.
