Hi, What is your favorite social network site and why do you like it? Mine one is You Tube and the reason I like is that I spend time there to get relaxed, watch all sort of videos from funny videos to some serious documentaries.
My favorite social networking site is Facebook and now I am also liking Google+... I think Google+ will soon take over Facebook..
I'm going to have to say that I love Facebook and Youtube. Twitter and Tumblr are very addicting as well.
Stumble upon, Digg, Pinterest, Diigo and tumblr etc. There are many High PR Social websites for traffic source.
There are lots of social sites for networking, but there i love Facebook and after that twitter and Google plus.
Youtube is really great but i don't get it as a social network really. There are only the comment feature where users can interact with each others. My favorite is facebook, because it is a social network to meet friends, exchange stuff such as videos, photos and more or play games, people are always online via their computer or mobile. It is the social network to market yourself and get traffic, to stay in touch with your friends and more...
I like Facebook and Twitter. Using these social media sites for promoting your sites are great because they have so many users. You get to know a lot of people as well.
