If you are a blogger, whether serious or for fun, it benefits to join Twitter. It is a great way to network with other bloggers and to give announcements and links to new posts or giveaways. MomAdvice gave a great explanation of Twitter and how it benefits you to use it.
To make the most of Twitter, you should post a link to your Twitter page so that readers can follow you. There are several sites that offer free Twitter buttons. If they don't have a code for you to add, then you simply save the button as a picture and add to your site, including the hyperlink to your Twitter page (for example, mine is www.twitter.com/readingtofour).
I was going to hunt down and list out all the places you can get cute, free Twitter buttons, but Annie at BlogU already did. Simply click HERE to see her post with lots and lots of links for Twitter buttons.
