At a lively workshop at the Des Plaines Public Library last night, I used "Julie & Julia" as an example of what can happen if a writer is motivated to start a blog. The Adult Service Librarian, Christine Posinger, shared another great example of a blog: The Pioneer Woman.
Take a look at the blog to see a perfect example of focus, great use of photos, the author's consistent "voice," and the wonderful platform created by a blog, links to her books, links to her Facebook and Twitter pages, and audio. It's a great example. If you're wondering where to start, the easiest way is... just start.
Go to blogger.com or wordpress.com and sign up for the free blog. Blogger is easier to use, but Wordpress has cooler designs and features.
