That's exactly the kind of answer I was looking for mooreindustries, thanks for posting.

Nowadays, people are using the social network sites to do marketing of their sites. But the main use of it is to make communication with customers, friends and to stay connected with them always.

aside from it being a great avenue to keep in touch with old friends and it being a means to meet new friends... not to mention all the fun things you can do there, social networking sites are a great tool to promote your site, blog, online business or what have you.... i have several accounts that link to my squidoo blog... if you find yourself in the 'neighborhood', feel free to drop by... cheers!

I've been toying with the idea of using them but I've not really had the time to do so. Maybe I'll do so soon... who knows!

social networking is also a good way to increase traffic in your websites, building reputation in social networking sites is very important.

social networks give you a sense of place in a disconnected world. For businesses, it can keep and build customer bases in a very competative and portable environment.

to boost something I have..
wisely..

it is one way of communicating with other people and having new friends

I'm interested in what others are reading and talking about. I don't have the time to go through all the web pages out there to see what's going on, so I rely on social networks to find the information in the topics I am interested in.

It is also an effective way of getting quality backlinks and because social networks involves people from all walks of life, your business could easily be seen and delivered through your own network of friends, relatives and colleagues. It could somehow build traffic to your site and improve rankings as well.
