I hate twitter and have never used it, but starting a new site and figured I better! How does messaging work? If I see someone on Twitter I want to message, can I just message them directly? Or do I do @theirname? Or how does it work. I assume celebrities must get hundreds of messages a day, so there must be something that stops it, no? Or do they have to follow me in order to message? Second, seems no one posts their email anymore only Twitter. So kinda ties in to the above, but how do I get in contact with them if they don't post email anymore, only their twitter?
