Many websites, including blogs, many newssites, and Twitter feeds, have an online presence that includes regular updates. Importing these pages' RSS feeds into a Feed Reader will keep you up to date on updates without having to remember to check a site regularly.
RSS Feed Readers are available in many formats. Perhaps the most popular are those that are web-based or a brower plug-in. Web-based feed readers are often more functional than brower plug-ins.
Weblogs (aka blogs) really became popular in the late 1990s. They are a subset of the Internet where a great deal of topical discussion takes place--whether that discussion be about fashion, sports, politics, or molecular biology.
Blogs are a great informal way of discussing new developments in a field. Comments on blogs allow for a wealth of discussion and provide different perspectives on an issue.
Students in subject specific or advanced classes can use blogs written by journalists, researchers, and practitioners, to keep up-to-date on new developments within a specific field or discipline.
