Do you love Reddit-style comments? Do you submit your blog post to Reddit only to find the discussion there is much more active than the one at your own blog? Do you wish you could show Reddit comments as they appear on Reddit on your own blog post?
With ReddiComments, you can! ReddiComments allows you to use a simple shortcode to embed ANY Reddit discussion in your blog posts.
Step 1: Submit your blog post to Reddit 
Step 2: Add this shortcode at the bottom of your blog post:
[reddiComments link=”http://link_to_your_comment_page_on_reddit”]
Step 3: Sit back and join the conversation on Reddit!
Please note: to get the Reddit comments, this plugin makes an external call to an API hosted at http://reddicomments.com. The only information it sends this API is the link that you provided – no private information is ever sent to or from the ReddiComments plugin.

It puts a bar of icons at the bottom of each post allowing your readers to submit your posts to several different 
social networking and bookmarking sites. (del.icio.us, digg, fark, etc.)
The original plugin was called <a href="http://blog.calevans.com/2006/02/08/notable-another-wordpress-plugin/" rel="nofollow ugc">wp-notable</a> 
but no longer worked or was supported. The author was Cal Evans.
