This site is very helpful in describing what Edmodo is and how it helps both the teachers and the students communicate better and get homework.

There are a lot of sites that look like they are very helpful. 

This could help with people get their ideas out there and to also help those that are starting their own business and need places to advertise.

This may look like a child's game, but I think that anyone that is taking either a marketing class or any class that has to do with business. It can help students understand what the teacher is talking about and they can also have more of a visual for what is expected of them.

This site can help students use different tools that are out there. They range from design tools to virtual world tools.

This site could give teacher and students alike help when they do a survey. Instead of using tallies or clickers, students and others could use their phone to take a survey and also be able to get quick responses.

This site helps be able to have web conferences in order to share their desktop but also ideas with people around the world.
