1. Why only one choice possible: Read or Love? Can't I have both?
2. Is the design customizable? I would like to have a heart "love" sign. Similar to the "Love it" badge on this site - http://www.premiumpixels.com/freebies/clean-simple-login-form-psd/
3. Is the functionality AJAX, i/e., it'll work even with a page/post that is cached?
