I'm a frequent user of Zap Reader—the popular, and free, web based speed reading program. There were already plugins for several blogs (WordPress, Blogger, and TypePad), but nothing for SharePoint blogs. I thought it would be nice to add a button to each blog post that allowed readers to quickly load the text into Zap Reader so they could speed read it.
The DIVs for the blog posts don't have unique names.
I couldn't add new FORM tags on the page.
You will find the code for the "Zap Read This" Button for SharePoint Blogs on the Zap Reader Tools page. The code is well documented to explain why I did some things the way I did. To use it, simply copy the code and paste it into a Content Editor web part on both the default.aspx and Lists/Posts/Post.aspx pages of your SharePoint Blog. You may want to customize the placement or look of the button, but this was written to give you just the basic functionality.
Let me know in the comments what you think!
