Web 2.0 is a broad concept given to the recently changing trends in website design, and is classified by sites that emphasize new or creative methods of information transmission, increased communication and collaboration between users. It is a secure and easy-to-use platform where users of any technical skill can participate.

Technical Aspects of Web 2.0 influence

RSS Feed

One of the most popular technical adaptations to the "Web 2.0" craze is the RSS feed. This icon, which is seen by your address bar as you read this very page, indicates that the website can be easily read or viewed from any device that reads the RSS format. It allows websites with frequently updated information, such as blogs, wikipedias, tweets, or message boards to publish that information in simple code that can be viewed outside of the website. Typically, these RSS websites have at least a few components that can be viewed on a cellphone or PDA, handheld video game systems like the PSP, and even some higher-end television and home theater systems. Many iPhone applications use this technology, because it requires less time to load an RSS feed than it does to load the entire website.

Searching Web 2.0

A good idea when searching for specific things on Web 2.0 is to first browse through the automated tags. I found it easier when I looked through the tags that were available instead of trying to search on my own. The tags are very tricky. For instance if you are looking for something for Math, there are different sites that come up for the term "Math" and the term "Mathematics." Because of the narrowness of the tags, my advice would be to browse through all of them before trying to search on your own. This way, you could find something that is helpful that you never thought of before.
With the added popularity of Web 2.0 tools, searching becomes even easier. It is now possible to search (in Google or another search engine) for a tool by typing something like "elementary math Web 2.0 tool." This allows a teacher to search for specific tools needed for lessons.
