I don’t understand the @ feature on Twitter. I’ve tried to send people messages but i don’t think that i’m doing it right cause i don’t get any responses back. Here are my questions.
1) Does the other person have to be following you to get your updates or to post an update bout you?
2) Can you send direct messages to people who don’t follow you?
3) How, exactly, do you compose an update to another person?
any other tips would be helpful!!
