If you don't have your own blog then you're my mother. Or one of her friends. Everyone else has a blog. And rightfully so. But what is Twitter?
Excerpt from Kikolani:
Updates that start with RT @username are called Re-tweets. This is an update where you repeat another user’s tweet. If a user posts a tweet that you want to share with your followers, you would just copy their tweet, and add RT @username. This gives them the credit for the tweet, and lets them know when they are reviewing their replies that you shared their tweet, which is something most users appreciate. It’s a great way to build good relationships with your followers.
The other great thing about RT’s is if you share something valuable, other’s will RT your update. This in turn will give you more credibility as a Twitter user who adds value to the community, and will probably result in more followers. So whenever you are reading a great article, it’s a good thing to take a few extra moments to share that article with your Twitter followers.
