I just found a collection of educational videos that explain different internet concepts in plain English, making it easy to understand. Here are couple of videos that I particularly recommend.

Social Media in Plain English

Podcasts and How They Work

Twitter. This is something I had to watch closely, since this is something I am not using on the regular bases. Basically, it is you blogging about what you are doing right now. This way people can know what is that you did 10 minutes ago, or 5 minutes ago. If you want to make your life public, this is a way to go. Cool concept.

Wikipedia, ever wondered how the biggest encyclopedia in the world works? Here is a video on wiki, (the platform behind wikipedia) and how it allows people to collaborate about anything they want. It is also in plain Enlish.

RSS and how to keep up with everything that is going on on-line.
