I don't know why you asked that question. Facebook is the no 1 social networking website. it is also in top10 websites of the world and @ no 1 spot among social networking sites. Also facebook is still bloggers first choice to promote their blog through.
According to me its facebook because from teen to adult to oldies,all are using facebook which shows that facebook is dominating the social media in mass
May be there lot social network like linkedin, tweeter etc...Facebook is only network where all having account.
thats true facebook is used by plenty of people so there will be lot of users on facebook with having their account
I browsed through these posts to see if anyone was using anything besides FB and Twitter. I'm glad people are making an effort to branch out to smaller networks, too. It might help to join niche networks that concentrate on a certain market. By the way, I like LinkedIn and Pinterest, too.
It truly depends on the way you go for the particular social media means to say that it depends on the target that you have locked so that you can build up the business in a very appropriate way with the use of the social media,to promote the brand and to build up the business mainly we go for Facebook because it has more popularity and lot of users are using this side which makes the particular brand to promote in mass.
You are right I am agree with you while i also suggest Facebook as it's user volume is huge. G+ is also a good Social site which can help you gain the traffic as well as helps in seo get more up in search results. While for a marketer Tweet is most important as it give you targeted and authenticated users.
