Twitter is a good way to promote yourself & take interact with friends and celebrities. You can post pictures and know you can upload music and share it with your followers. It's also a good & quick way to get world wide news and music & entertainment news before it hits the streets or media. I even knew about the MJ death before the media because of Twitter,I forgot which Celeb,but one celeb said she seen MJ being carried out of his home on a stretcher,she tweeted it and it blew up from there really. Also if you want to keep things private you can always have a private page,which if you follow other people and your page is private at the time,people can't see your @Replies to them because your page is then private,but to each it's own I guess you could say when it comes to that. I've been on Twitter for a good while,I have 800 followers,I've talked to friends,but I promote for and celebrities,like Jenna Jameson and rappers & Vh1 Reality Tv Stars. But I would really say just sign up and try it to anyone who don't have a twitter & make sure you look in my sig and follow me from the link in the picture that is shown in my sig.
