Questions about Twitter?

[Roxanne]

What does RT @ and # mean on Twitter and all the other symbols people use?

[I♥MJ]

Like @ means its at a person, and The person they did it to can view what That person wrote to them.

"RT" is used to signify that you are reposting a twitter update from another user.. it is usually followed by the "@username..."

@ symbol is used primarily to address another twitter user..
ex. say your friends screenname is "twituser," in order to address them or reply to them in a tweet, you'd type;

@twituser *and your message here*

the # symbols basically connect your twitter comment to a bunch of other twitter post that relate to the "#"
for example:
#thankfulfor (is a post including things your thankful for)
#monkeys (your post will be included with other posts including monkeys)

it's not necessary to use.. but to gain more followers.. for more go here..
