That's right and iam aggre with you... Both is most popular of social network, because most people used that to sharing information, and also promote business...
I think till now, these social networking sites are big enough for marketing. Other Sites are still not come upon. So i fix with myspace, facebook, and twitter only.
It seems like Facebook, Myspace and Twitter still dominating this field. So far there is no site yet that will seems to emerged to follow the footstep of this 3 social networking site. But if Rotatrix if just going to improve more of its system they would have chance to follow this 3 but as of now no social networking site yet to become much bigger this 2010 unless the trend will set another record.
i think these 3 social media site are remain top position till next whenever new Social Networking Site site with unique consept like Twitter . Better and new concept always accepted so try to live unique Social Networking Site.
Seeing that facebook is number 2 in Alex rank list (1 is google........), i dont see that anyone will be challenging Facebook. Myspace is useful for Music artists and generally used by Younger generations (In my experience), where as Bebo is used as a neutral etc. Regards,
Facebook will remain on the top among all social networking website. If anyone can give competition to facebook so it is twitter.
