How do I configure my site so that the main page functions like a blog, showing only the first part of each post, with a link to "continue reading" for folks to click and shift to a page with the entire post and comment section? If it matters, I'm using the twenty ten theme. I know of other wordpress sites using that theme which function as I want mine to - for example, wattsupwiththat.com
Thanks in advance for your help!
The blog I need help with is rationaldb8.wordpress.com.
