You can't know, unless you look in their favorites.
To tweet on your twitter account, log in to twitter and you should be taken to a page that says, "What are you doing?" Just type in the box whatever it is you want to tweet to your followers and click update.
just tweet him on twitter
You don't tweet just about people, you tweet about anything, and when you do tweet about people, its not all bad. Twitter.com is awesome.
The first tweet on Twitter was "just setting up my twttr"
Yes just type their username into your tweet.
just go to there profile and tweet them.
You may send a tweet (or @reply) to anyone on Twitter; you certainly don't have to be following them! Following a Twitter user just means that all their tweets appear in the "timeline" on the home page of Twitter when you log in. (Along with your tweets and the tweets of anyone else you may be following.) To follow someone, go to their Twitter page and click the "follow" button. Anyway, to send a tweet to any Twitter user, just include an @ sign followed by the username of the user you want to send the tweet to. For example, if you want to send a tweet to the user with the username JohnSmith, include @JohnSmith in you tweet.
You don't really talk, you tweet! You leave messages for other users. Like, if you want to say hi to Twitter user MrExample, just tweet '@MrExample hi'. Minus the inverted commas. The tweet will come up at your homepage and in the @replies page.
Yes... Just copy the object code from youtube or whereever you host it and "tweet" it. :)The guy above me is wrong, you currently cannot post any HTML codes on twitter, you can't embed videos. You will have to just "tweet" a video link.You can share music on twitter at: http://www.imusictweet.com
i just copy the tweet, paste, then put 'RT' at the start of it and send.
You can use the hashtag the way you normally do - just tweet it.
You have to have a twitter account. I would suggest you follow Anthonysmosh and iansmosh and then their main twitter account smosh. anthonysmosh is normally the one who will tweet asking for twitter question, then you would just reply to his tweet and ask you question. Smosh rule >.<
