I really Facebook because of all he different options... It all depends on what you want to do... Twitter just gets the word out but u cant type as much in their box.... Not a big fan of twitter.
fifty fifty, i like the tagging in facebook. Twitter is powerful in real time news. Both are powerful tools in IT services.
I love facebook more because I very familiar with it, I have a twitter account but forget the accnt coz im not using it. my fault..
Yeah, I believe Facebook is better, more options, more applications, and more social network, twitter is more spammed i think.
