What is Twitter? It's a free blogging site which allows short status updates of 140 character or less. You can share links, post pictures, and follow others.
Sound like Facebook? It sort of is like FB's news feed.
How do I start? First you create a profile. Represent yourself with a picture, a general location, a website, etc.
Who should I follow? anyone you want to? I use my Twitter account solely for writers, publishers, and agents.
What do I tweet? Anything you want to? You can tweet about your life, things that happen to you, your thoughts, inspirational quotes, or anything that will fit into the 140 character space. I like to mix up my tweets with my own, re-tweets of others who I follow, and re-posts from blogs or articles I find interesting. My daily rule is to post at least 3 of my own tweets, 1 re-tweet and 1 reply tweet.
How do I reply? The @ symbol precedes a tweeters name. Replying to a tweet with @ makes a conversation.
Retweeting. When someone else has a tweet that you want to share to your followers, you retweet it. To comment on a tweet, use RT and the entire tweet including the name of the original tweeter.
Direct Messages. Also known as DMs. This is a private message between tweeters. You can only DM someone who you follow and who follows you. It's like an email program kept inside Twitter and using the above rules.
What is a hashtag? It's a tagging system to use to include in a conversation. By putting # in front of a word, creates a link. Then you can search on conversations with that hashtag.
