What Wordpress plugin is this one?

I'm having trouble identifying a plugin (or perhaps is not even a plugin), but can you tell me what plugin outputs the section at the bottom of the post that has the headers: "Did you like this article?" and "Related Posts", and has a list of bookmarking links, and a list of posts respectively.

Image of the stuff I'm referring to:

Example URL: http://www.escapefromcorporate.com/networking-tools-and-help-upmo/

Edit:

Thanks for "Related Posts" plugin references. Now, for the other one (Did you like this article?), it is a really mysterious plugin. :) I'm thinking it is in fact a plugin since you can see other websites with almost the exact same options at:

Any hints? :D

Thanks!

That would be Yet Another Related Post Plugin and as for the sharing one that could be a number of things. A lot of third party sites, like AddThis and ShareThis provide these social media widgets. They make plugins for WordPress and give you the option to implement raw code for their widgets and are fully customizable via CSS.

AddThis and ShareThis both provide tracking analytics as well. That's always a plus.

If you don't want to use AddThis or SharThis, try this top rated Sociable plugin on WordPress' Plugin directory.

SexyBookmarks is another popular plugin with similar functionality

If you are going to do related posts. It requires a bit of overhead on the admin side, but pays off in performance increase down the road. Try efficient related posts

The "Did you like this article" section seems to be a set element of the theme, not a plug-in. Many of the other sites you listed use the same or similar themes as those available from Jestro and Theme Foundry. I think you're looking at a built-in function, not something easily portable without purchasing one of the themes or looking at the PHP code.

However, you could build the same thing with a text widget ... just place your own social bookmark codes in place of the ones you see on other sites.
