Surprisingly, some people believe these changes are bad. First, they point to a debate about online property rights. People who make web pages may not be aware of these rights. This means that some links to online information might not be legal. Second, the critics say we cannot trust online information: anybodycan publish a blog or make a written contribution to Wikipidia. They say that traditional encyclopedias and newpapers use editors to make sure that information is correct. But these critics can’t be aware of the research into the number of errors between online and printed sources of information. This research has show almost no difference. Other people argue that the Internet is changing the way we read: we jump from page on the internet, and we are losing our ability to focus on a single topic.
