How to add Web 2.0 buttons to Blogger Beta

As unfortunate side effect of upgrading from the old Blogger to Blogger Beta, web 2.0 buttons stopped working. Here's a quick guide how to get them back. Enter Dashboard, select "Template" and "Edit HTML". Select checkbox "Expand Widget Templates". Now locate the following fragment (or something like that):

<p class='post-footer-line post-footer-line-3'/>

And replace it with the following code and save:

<p class='post-footer-line post-footer-line-3'>
Add to:
<a expr:href='"http://digg.com/submit?phase=2&amp;amp;url=" + data:post.url + "&amp;amp;title=" + data:post.title'>
<img src="https://photos1.blogger.com/blogger/1785/2897/1600/digg.gif" /> digg</a>
<a expr:href='"http://reddit.com/submit?url=" + data:post.url + "&amp;amp;title=" + data:post.title'>
<img src="https://photos1.blogger.com/blogger/1785/2897/1600/reddit.png" /> reddit</a>
<a expr:href='"http://del.icio.us/post?url=" + data:post.url + "&amp;amp;title=" + data:post.title'>
<img src="https://photos1.blogger.com/blogger/1785/2897/1600/delicious.gif" /> del.icio.us</a>
</p>

Now you should have Digg, Reddit, and del.icio.us buttons below each of your posts.

Technical details

Special hacking is needed, because buttons cannot simply submit the current URL. The reader might be reading blog main page or one of archive pages, not necessarily posts' page. The code is rather straightforward. expr:href is executed and becomes href. data:post.url is post URL, data:post.title is post title, strings are quoted, + concatenates. It seems necessary to double-quote special characters like & to &. You can put the buttons somewhere eles within <b:includable id='post' var='post'>...</b:includable>. Support for different web 2.0 services, different images etc. should be easy. If you have any questions, don't hesitate to ask.
