Reddit

Reddit is considered the front page of the internet, with thousands of topics to view and comment. I would advise this tool be used for high school students because of the language. There is a very good chance that your high school students already use this social/resource platform.

Martin I explored the Reddit site a bit and it looks interesting.  It seems a lot like Newsela which also has a ton of interesting articles.  I work with kids who struggle with reading and the task is that much harder if the student is not interested in the article.  This looks like a variety of topics like Newsela which the students crave.
