Rate My Professors

Recently I got an email from my friend about this site where students can rate their professors. It also helps the students who are searching for their supervisors. They can first search for where they are going to do their research or other. Then they can choose their professors according to their rates.

So the guys they know the supervisor well can use this site to rate their professors , might help for the others.

Social Networks

The nodes in the social network are the people and groups while the links show relationships or flows between the nodes. I recently got to know about Facebook, one of the popular social networking service. I have been using LinkedIn for sometime and it's not new for me. Today I got an invitation from my friend to join in another social net working hi5.

There are several social net works. But it is good to have a membership of some of them. So we can have a doubt which links should suite to us? It depends on which type of relationships we want to have with others.

Here I am giving the usage of following social networks.

Hi5 - General
FaceBook -Started for colleges, then high schools, and now everyone.
LinkedIn- Business

The following link gives the detail of the award for the top social networks in 2006.
