Google Reader is a RSS which is a good form of sourceful information filtered when looking up using key words for example "education". It can be a useful tool in the classroom as rss is a filtered safe internet site and can be monitored closely by educators and it also has links to useful internet sites that can be uploaded by teachers.
RSS is short for 'Really Simple Syndication' but sometimes known as 'Rich Site Summary' which is a family of web fed formats used to publish frequently up dated blogs. RSS could be used in schools for students and teachers to be able to keep up to date on the specific web pages and current news events that they are interested in.
RSS users have the advantage of security by not having to search for their favourite websites and signing up for newsletters, saving them time and making it very convient for them.
I have found a great link that has all information required for all information necessary on RSS and the positive reasons to have it in the classroom or office. http://www.whatisrss.com/
