So I've been meaning to play around with a PHP / Java Bridge as well as the Blogger API, so I figured why not to both at the same time. I have briefly used the phpatomapi, which getting to use with the blogger beta is next on my list of things to do (also while i work on blog comments using this bridge). Also to add to this is being able to display/edit/add comments to the posts displayed.
Coding Library: PHP Java/JSP
