Facebook and twitter rare the best social networks for communicating people around the world and the reason is clear. These social networks have the most users on the net and it makes them such popular for both usual use as a social network and business purposes.
Facebook is definitely first. They have the biggest general population giving you a chance to advertise to lots of different markets.
I would have to say Facebook too, though I don't always like that it shares everything u do, if u allow it too, I don't want my youtube comments to be on facebook, kind of annoying, apart from that yeah it's the best of of them, twitter i never really caught on too, who's gonna see/read your comments when there's so many people constantly posting.
I prefer Facebook, that a fantastic web2.0 platform for Internet Marketing. It consists attractive applications, different way of representation to show your product and services through links, video, albums and pictures. It is better to another one because it provides a platform not only web promotion expert as well as general users also.
My Vote as well goes to Facebook. because users are more for facebook than other social network. 2ndly i say Twitter.
I am not a big fan of social networks cause I here so many stories about things that can happen but I do not even let my 10 year old on it but I do have to say that tweeter and face book are more popular and more social then my space
Every social network has its own positive and negative sides. In my opinion Twitter marketing is really awesome, if it's done well, but Facebook isn't bad neither
In my opinion, facebook is the best social media for long term business, and twitter just for broadcast only (Get instant traffic within a few minutes) ... Myspace just forget it , don't waste time.
