The disadvantages of using the internet for research purposes

Personal Opinion: The internet is the main source of information, which meets the needs of many users all over the world. It is very helpful in that it helps its users to clarify certain topics, problems or issues. However, although the internet is very essential in that it provides needed information to its users, there are also disadvantages associated with it. For example, there are hackers or intruders who may have access to the information and damaga or destroy it; along with helpful and relevant information there are also distractions to the user in the internet (especially to young people or students) which may hinder them from using the internet for the intended purpose (eg.pornography, advertisements,etc.);the information may be updated, deleted or wronly explaned, making it inaccurate.

to the facts of the subject matter you are reporting on or writing about. While many writers, today, tend to rely solely upon the Internet, there are many disadvantages to using this as a sole resource tool. While the Internet has provided a great resource for gathering information quickly, many writers and journalists are relying upon the Net as a sole source of information. When this occurs, credibility can be diminished if the information gathered is of poor quality or is inaccurate. Whether you are a writer for publication, Internet content, blogs or a Content Producer for Associated Content, there are some key issues of concern when conducting research on the Internet. While most reporters, journalists and writers are familiar with the issue of quality and reliability, all too often, we find information via the Internet is convoluted and far stretched from the original facts. Therefore, rule number one when using the Internet for research: Be sure your source is credible. Another disadvantage to using the Internet to gather information lies in the countless hours a writer may spend in gathering information; weeding through spam, hyperlinks, inaccurate reporting and blogs. For this reason, many writers, including Content Reporters and journalists, should set a pre-determined amount of time, each day, limited to Internet research. Disadvantages to research legal documents often falls in the issue of what is known as decontextualization; a process by which you may be able to gather an excerpt of piece of information from a document rather than reading the entire document. The result is the loss of true context or meaning of the subject matter.
