RSS

"Rss (Rich Site Summary or Really Simple Syndication) is a type of web feed which allows users to access updates to online content in a standardized, computer-readable format. " (Wikipedia) 

When the RSS reader is opened it checks all the blogs and web sites that you're following. And let you know if there is something new. All you have to do is downloading an RSS reader. I use feeder.

And these are the websites I'm following:

Free-Range ELT is one of my favorite. It's a really useful blog owned by Kathy. When I read her blog I feel like she's a friend of mine. There are really good stories about ELT. And also some useful info.
