Ok, so you reply to someone one of two ways. First, you can click the “reply” option. On Twitter.com, you hover over the tweet you want to reply to, and it gives you various options like Favorite, Retweet, and Reply as well as the time it was tweeted. Or, you can simply type in the username you’re trying to reply to with ”@” (no quotation marks) before it. So like to reply to my tweet, you would go @Aethelflaed Omg, yr so right!!!!
To privately message someone, aka a Direct Message (DM), you type in D username and then the message. So to DM me, you would put D Aethelflaed Hey, you wanna grab Thai food tonight? If you get a Twitter client, like Tweetdeck, it has options on each tweet to DM the person.
To retweet someone, which you do because their tweet is so awesome you feel you should tweet it too, but don’t want to plagerize, you put RT before the tweet. So my tweet “I wish @google would learn which subsearch engines I use and show those first – like books, scholar, and news, NEVER recipes…” would become “RT @Aethelflaed I wish @google would learn which subsearch engines I use and show those first – like books, scholar, and news, NEVER recipes…” or if you want to comment, “Omg, so true! RT @Aethelflaed I wish @google would learn which subsearch engines I use and show those first – like books, scholar, and news, NEVER recipes…”
Ok, those are the biggies, anything else?
