It’s probably not a milestone that will be celebrated anyone, but Twitter is now more popular than MySpace. Figures released by comScore show the microblogging site chalked up 96 million unique visitors during August while its rival managed 95 million. I get this message from this site - http://www.infinitepath.co.uk/20100929/social-media/twitter-passes-myspace-lags-behind-facebook/
well, after Live Windows Life ends and transfers to WordPress, maybe they will be another player in social network game.
Twitter is something different than Facebook. The way it facilitates dialogue is simpler and in my opinion, more effective. They serve different purposes and they work well together, so I think they play off each other fairly well.
I don't see Twitter surpassing Facebook. Facebook is so widely used by so many generations. Both have different uses, but complement each other well like another poster commented.
Well it´s no suprise is it? You know all the smartphones out there today? (Almost?) All of them have Twitter and facebook preinstalled (as bloatware.) as a app. With so many new smartphones user as it is, Twitter will not fall behind...at least not this year.
