How do you reply to a tweet on twitter?

[Tweet]

It depends if its on your phone or on web. The phone has only a few options from the menu, but if you type @ username in the beginning of any tweet, then it is a reply. Just like if you type DM username it will direct message and not be visible to your followers. You should check out http://tweetcustom.com that has a long list of Twitter sites that have tools to help out. Some use auto reply program that allows u to automatically send a message when someone follows u, like Thanks for following, its pretty cool. They also have a celebrity list of all celeb accounts. Good luck and welcome to twitter!
