“Keep the visitors glued to your site for long” This is what every 
blogger out there wants to do. The Recommended Post slide Out Widget 
does just that. It’s kind of  an invitation to the reader to read a new 
post once he has read one of your blog entries. You might have seen this
 kind of a widget on many popular websites like New York Times, 
Mashable, Times of India etc.
I too loved the idea and found out that some one else had already 
made a jQuery snippet which does just the same. You can read about this 
awesome code on Mary Lou’s blog at 
http://tympanus.net/codrops/2010/04/13/end-of-page-slide-out-box/
I have made some modifications to the snippet so that it gets loaded 
asynchronously without affecting the page load. The Slide out will show 
random posts from your Blog. The random posts are fetched from your Blog
 Feed using Ajax.
Demo of the Slide Out
Scroll down to the bottom of the post and you should see the Recommended Slide Out.
Add the Recommended Post Slide out Widget
To add the widget to your blog, you can use this one click installer.
Customizing the Recommended Slide out
1.
 End Of Post marker – The slide comes out when the
 user scrolls down to a particular point in your Blog.(the bottom of the
 page by default) To mark this point, you can add an HTML element there.
 The element should have the id 
bpslidein_place_holder
e.g.: <div id=’bpslidein_place_holder’></div> would do 
the job. The best place to add this marker would be at the end of the 
post. If you want to do it easily, you can add this to your Blogger 
Template.
In your template Find,(You will have to expand the Widget Templates)
<div class='post-footer-line post-footer-line-1'>
or
<p class='post-footer-line post-footer-line-1'>
or
<data:post.body/>
Immediately below any of these, add the following snippet and save our template
<b:if cond='data:blog.pageType == "item"'>
<div style='display:none' id='bpslidein_place_holder'></div>
</b:if>
Now when the reader scrolls down to this div, the slide will open up.
2. Customizing the Look and Feel of the Slide out.
You can obviously style the Recommended Slide out. But before you do 
that, you have to add this variable definition to your template
<script>var bpslidein_custom_css=true;</script>
This should be added somewhere above the Slide Out Widget. If this 
variable is not set, a default StyleSheet will be used to spice up the 
Recommended Slide out.
Once this variable is set to true, you can add your own CSS definitions. You can add your CSS at 
Template Designer > 
Advanced > 
Add CSS
This is the default set of Style definitions applied to the Widget. You can modify them and use it.
