Up till now (9/4/2010), you had to CHOOSE between having either the Facebook SHARE button OR the Facebook LIKE button for your blog posts.
Well, I just figured out how to have BOTH available.
Here is my site to get a visual of what it looks like ► ► ► http://jcrylequotes.com/
► Follow these short, easy directions to set it up on your blog:
1) Your Dashboard
2) Settings
3) Sharing
4) Under "Available Services" click "Add a new service"
5) For "Service Name", type in Facebook
6) For "Sharing URL", copy this link ► http://www.facebook.com/sharer.php?u=%post_url%
7) For "Icon URL", copy this link ► http://cdn.iconfinder.net/data/icons/Classy_Social_Media_Icons/16/facebook.png
8) Click the "Create Share" button
9) Drag and drop your Facebook SHARE button to either the "Enabled Services" section below the "Available Services" OR over to the right with the WordPress SHARE button.
10) Now, simply click the right down arrow on the Facebook button (not the button you JUST created; the other one provided by WordPress) and choose the "LIKE" option, save everything at the bottom of the page and you're all set.
You now have both the SHARE and LIKE options available to you at the bottom of your posts.
